▼ Doping of transition ions and introducing oxygen vacancies (VO) in several oxides can trigger spectacular room temperature ferromagnetic coupling and becomes diluted magnetic oxides. How the magnetic dopant and vacancies collaborate to induce ferromagnetism is still unclear. A general picture of the carrier mediated mechanism is widely accepted, such as: the free carriers mediate the long-range magnetic coupling via RKKY mechanism when the material is in metallic state while the localized carriers mediate magnetic coupling in a limited radius via BMP mechanism. For those semiconducting materials, the carrier is neither as free as metals nor localized as insulator, how electron induces magnetic coupling and who provides magnetic moments and what are the roles of doped transition ions and introduced oxygen vacancies are unclear and are needed to be answered before real applications. This study aims at developing a technique to reliably reproduce oxygen vacancies in Co doped ZnO films and growth a series samples with systematically varied oxygen vacancies to study these mentioned issues. In this study, five percent Co doped ZnO, Zn0.95Co0.05O (CZO), targets were prepared by solid state reaction method at 860 °C. CZO films with various oxygen vacancies were grown by RF sputtering technique in a mixed H2/Ar gas with different percentages, denoted as H2%. It was found that the base vacuum of growth chamber is crucial for reliably reproduce exact vacancy concentration. With our effort, the base vacuum of our chamber is now lower than 1x10-7Torr and the VO reproducibility is reliable. These as grown films degraded very fast when were exposed to air. In order to know basic properties of the as grown films, the resistance and optical transmittance were measured right when films were taken out from the growth chamber. Films grown in high H2% atmosphere exhibit lower resistance, higher transmittance and wider optical bandgap which could be due to Burstein-Moss effect. The effective oxygen vacancies were measured by X-ray photon emission (XPS). Due to XPS is accessible in the core facility center which is usually few days or week after the film growth, only the data at the mid layer of films were taken. A slightly discrepancy between H2% and XPS data is found indicating a small uncontrollable in our film growth system. Reliable data has to be taken for only the as grown films. MCD data proves the doped Co ions substitutes successfully at Zn sites and shows magnetic coupling at around 3.4eV same as SQUID-VSM data indicated. These data strongly indicates that the doping of 5% Co alone cannot generate magnetic coupling, and only when coexist with oxygen vacancies the magnetic coupling appears.

▼ One of the most interested topic in ZnO series diluted magnetic semiconductor is the role of oxygen vacancies. It has been shown that the oxygen vacancies and interstitial hydrogen ions can be generated when introduced hydrogen gas during the film growth depending on the growth temperature. The main goals of this study are to understand the effect of the added hydrogen during the growth of pure ZnO and Zn0.95Co0.05O films on the generation of oxygen vacancies and the effect of oxygen vacancies on magnetic coupling. Two series of films, ZnO and Zn0.95Co0.05O (CZO) films, were grown by a standard RF sputtering technique. N&K optical measurement indicates the optical transmittance is lower by increasing the percentage of H2 in the growth atmosphere, which is denoted as H2%. Because the total growth pressure may control the mean free path of sputtered particles and indirectly affects filmsâ thickness which affects the quality of crystal grains. It is found that the crystal quality is better for films grown at 50mTorr rather than that at 130mTorr. The oxygen vacancy may introduce shallow donor band that enhances the electric conductivity, the film grown at 50mTorr has a higher electric conductivity than that at 130mTorr, as well. One important result of present study is that the doping of Co in ZnO films may enhance hydrogen effect and generates more oxygen vacancies in CZO films when were grown at the same growth condition as the pure ZnO films. Therefore, CZO films shows strong optical scattering lowing the optical transmittance. MCD measurements manifest obvious deep curves around 34eV which indicate that both series of films exhibit magnetic coupling under an applied filed, in which, CZO has stronger magnetic strength. However, the MCD is linearly dependent on the external magnetic field indicating a paramagnetic coupling. No room temperature ferromagnetic are observed. One important result is that the existence of magnetic coupling in pure ZnO film indicates that oxygen vacancies may trap electrons and preserved certain magnetic moment.

▼ SrRuO3 (SRO), which exhibits a ferromagnetic transition around 165K, is widely used as a conduction layer in multilayer system. However, the origin of FM, transport properties and the effect of Weyl fermion nodes below Fermi surface are still unknown. In addition, many people are also interested in the result of Hall measurement. During literature review, we found that there are still two unsolved problems. The first problem is about the physical mechanism of the anomalous Hall conductivity dependence with temperature in SRO films. Two different theories have been proposed to explain it. Since there are defects or impurities in a material, some researchers believe that it might be due to electron or impurity scattering, such as skew-scattering and side-jump scattering theory. However, in recent years there is another theory associating with Berry Phase mechanism, which is from the intrinsic nature of the material. In 2014, it has been suggested that the anomalous Hall conductivity partially contributed by Weyl nodes under the Fermi surface. The second problem is about ordinary Hall coefficient (RH) which exhibits a sign change from negative to positive with the increase of temperature ie. the charge carrier is changing from electron-like to hole-like. There is no exact reason and no complete model to describe this phenomenon. Therefore, the goal of our experiment is to solve the second problem about the sign reversal of RH. We have grown films of thickness 181nm and 275nm by pulsed laser deposition (PLD) technique. The X-ray diffraction results show that it is a good quality single crystal film. We have done Hall measurement from low temperature to high temperature with varying magnetic field up to maximum of 1 Tesla. We can see a clear square loop which proves anomalous Hall effect at low temperature. The Hall coefficient versus temperature plot (RH-T) is found to independ of Curie temperature (TC) and always exhibits a maximum value at high temperature. Finally, we propose a new theoretical model about two-band model along with impurity state to explain the whole situation. We find that the impure state is the key to cause the sign reversal, must be near the Fermi level and strongly coupled with conduction and valence bands. At present, we have a completed progress on this issue, but we still need to explore what is the origin of impurity state in the SRO films which may be due to Ruthenium vacancies generated during growth or to other unknown reasons. Further study is needed, and there are many challenges ahead for us to overcome.

▼ Triplet superconductivity was proposed in 1958, two years after the discovery of BCS theory and became significant in the modern years for it is possible for new applications such as the nondissipational spintronic. However, triplet superconductivity was realized only for low-Tc-superconductor/ferromagnet heterojunction, and no further development since 2010, when the last experiment was conducted. To explore the possibility of triplet superconducting state in high-Tc-superconductor/ferromagnet system, this research aims to develop and study the physical properties of La0.67Sr0.33MnO3 / YBa2Cu3O7-Î´ multi-layer film grown on SrTiO3 (001) substrate. Pulsed laser deposition (PLD) was the deposition method used to grow YBCO single layer film, LSMO/YBCO double-layer, and LSMO/YBCO multi-layer film on STO (001). YBCO single layer film was grown for varying growing temperature, varying growing pressure, and varying number of laser pulses for a laser frequency of 5 Hz. LSMO/YBCO double-layer film was grown for varying growing pressure. LSMO/YBCO multi-layer film was grown for varying number of pulses used to grow the LSMO film for a laser frequency of 5 Hz. In order to study the physical properties of the film, Resistance-Temperature (R-T) and Current-Voltage (I-V) measurements, X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) were carried out. For the growth of the YBCO single layer film, the optimum growing conditions were found to be 830Â°C, 200 mTorr, and 6000 pulses. For the growth of LSMO/YBCO double-layer film, the optimum growing pressure was 200 mTorr. For the growth of LSMO/YBCO multi-layer film, the film obtained a root mean square (RMS) as low as 0.80 Â± 0.07 nm, a d005 spacing of 2.3388 Ã with the lowest percent error of 0.0170%, a critical temperature (Tc) of the YBCO as high as 87 K with an onset at 90 K, and a transition temperature (TP) of the LSMO as high as 353 K. Moreover, our preliminary Ic-H measurements show that Ic decreases with stronger applied magnetic field. Whether or not these results indicate the existence of triplet superconducting state, no conclusion at the present state and further studies are needed. At least, these obtained data shows that the LSMO/YBCO multi-layer film was grown successfully on the STO (001) substrate. Our future plan is to conduct X-Ray Magnetic Circular Dichroism (XMCD) measurements to determine the magnetic properties between the interfaces of the heterostructure, and test the triplet superconducting properties of the material.

▼ Co-doped ZnO (ZnO:Co) thin film with room temperature ferromagnetism and spin polarized carriers is one of the advance materials and highly applicable in future development in spintronics. When ZnO:Co films deposited by a Î´ growth method in a ion sputtering system, low solubility of Co (3.75%) limits further applications such that a single-guns sputtering thin film growth technique is employed in this study to outreach this limitation. A ZnO:Co bulk with 5 at% of Co was formed by a solid reaction method and used as a target. ZnO:Co films were grown in a single-gun RF sputtering system. However, all films grown at room temperature were insulator which might because sufficient oxygen content in the target and the negative charge of oxygen ion moving toward substrate making the films of full oxygen content. In this study, the post annealing in vacuum environment and the deposition of films in hydrogenation environment are conducted to try to produce various level of oxygen vacancies in the films for understanding the interplay between the oxygen vacancies and the electric transport and magnetic coupling. The present experiment contains two parts: (1) grow films with various thicknesses by controlling deposition time and then applying post annealing process, and (2) grow the films in oxygen reduced environment by introducing hydrogen during growth and taking out partial oxygen content in the plasma and the films. In the first part, the grain sizes of the films are near constant while the crystal quality is improved with the thickness of films. The worse crystal quality of grains, the better the electric transport and the stronger the magnetic coupling after post annealing processes. This indicates that the electric transport and magnetic coupling could be improved when the thin films was formed by crystals with certain disordering and contained a certain level of oxygen vacancies. In the second part, the introduced hydrogen may combine with the oxygen sputtered out from the target before deposition on substrates. It means that the films are grown in oxygen deficient conditions and result in various degrees of oxygen vacancies. Zn clusters precipitate in films when the concentration of hydrogen is over 20%, and at the meantime, they increase the conductivity and suppress the magnetic coupling in the films. These discoveries provide new perspective in understand the electric transport and ferromagnetism mechanics in DMS materials.

▼ The most widely used transparent conducting thin films, Indium-Tin-Oxide (ITO), will surly encounter difficulties for Indium is naturally limited and its price rising fast very year. Searching for Indium free transparent conducting oxides (TCO) becomes one of the important issues in this field. Among of which, ZnO:Al (AZO) is the most import candidate and is used, now, in photovoltaic industry. In the future, flexible substrates are necessary, therefore, to preventing degrading of TCO crystal by repeatedly bending, TCO should be produced in amorphous or nano-crystal types. By properly doping of Ti in ZnO lattice, a certain form of amorphous-nanocrystal mixture films can be obtained at room temperature. Unfortunately, amorphous or nano-crystal with poor crystal structure suppress the electric conduction. Growth films at few hundred degrees may enhance the crystallization, however, the flexible substrate, such as PET, can only sustained temperature lower than 150 °C. In this project, an UV assisted film growth technique is used to study the effect of the UV assistant growth on films properties. The aim of this study is wish to grow films with better crystallization at lower growth temperature. Physical properties of films are investigated by the transmittance spectroscopy (N&K analyzer), X-ray dffractometer (XRD) and atomic force microscopy (AFM). It is found that the optical band gap increases and shows an obvious blue shifting due to the short range order in the present films. All films exhibits high level of transparency in the visible range. The grazing angle incident X-ray diffraction (GID XRD) indicates that high ratio of amorphous phase for films grown at high working gas pressure and low RF power. For certain growth conditions, pure amorphous films can be obtained. Oppositely, films grown at low working gas pressure and high RF power manifest crystal growth along all directions resulting shifting and broadening in XRD peaks. Higher the Ti doping levels higher the amorphous ratio. By gown films at higher temperatures, (002) peak dominates the GID XRD measurements. It is found that the 266nm UV assisted growth enhances crystallization and roughness of films at relatively low temperature, lower than the highest sustainable temperature of PET.

▼ The roles of hydrogen induced defects in pure ZnO has been studied extensively. However, in a transition metal, such as Co, doped ZnO thin films the effect of hydrogen in electric conduction and magnetic coupling is still unclear and needs further study. Recently model predicts that hydrogen can be a shallow donor as well as an agent to induce ferromagnetism coupling between two adjacent Co ions which substitute the Zn sites at room temperature in a ZnO sample with a high Co doping ratio. However, the experimental supports is rare. In this study, Co-doped(5%) ZnO films are grown by a RF-magnetron sputtering system on glass substrate at room temperature. The growth condition is fixed for RF power in 200W, working press of 70 mtorr and various mixing ratio of H2/Ar+H2 gas. The crystal structure, electric and optical properties and the influence of vacuum annealing on the samples are studied. In this research, we found that the doping of hydrogen in Co-doped ZnO thin films truly increases the electric conductivity which is proportional to the H2/(Ar+H2) ratio. When the ratio of hydrogen is low, the (002) peak taken by a Glazing Angle X-ray Diffractometer dominates, while increasing hydrogen ratio other diffraction peaks appear, indicating an enhancement of crystal structure in all directions, and grain sizes and unit cell volume decrease. From the optical transmittance measurement, it is found that the color of films turned into metallic like and the optical band gap increases linearly with H2 ratio which can be attributed to the Burstein-Moss effect that corresponds to the increasing of carriers in the conduction band by doping of H2. The transmittance data provides the information of the ratio of crystalline and amorphous, which can also be correlated to the AFM results. When the H2 ratio is higher than 30%, more crystals and larger sizes of grains were formed in the films, such that carriers did not need to pass grain boundaries so frequently and experienced less scattering that was actually improve the electric conductivity. The electric conductivity can be even improved by post annealing in H2 environment. Moreover, the Magnetic circular dichroism (MCD) measurement shows that the Co2+ ions does truly substitute on Zn sited in Td symmetry during thin film deposition. The resistance measurement as a function of temperature found the hydrogenated Co-doped thin films are semiconductor conductive. More works are needed to determine the magnetization, identify second phases and Vo by SQUID and X-ray photoelectron spectroscopy.

▼ In this study, the structure of four ultrathin germanium nanowires (GeNWs) were predicted by big-bang method combined with basin-hopping method and Stillinger-Weber potential. The thermal, mechanical and electronic properties of the GeNWs were further examined by density functional theory (DFT) and molecular mechanics. Not only the physical properties of GeNWs but also the absorption and diffusion behaviors of Li ion on GeNWs were investigated. For thermal properties, the phonon densities of states (PDOS) of four GeNWs were calculated, and the melting points of GeNWs were also predicted by molecular dynamics (MD) simulation. There are three types of GeNWs (helix, pentagon, hexagon) can remain about 400 K, but the 7-1 GeNW is melted about 230 K, which indicates that 7-1 GeNW is unstable at room temperature. Therefore, the 7-1 GeNW was excluded from post simulations and disccustions. In mechanical properties of GeNWs, the yielding stress and Youngâs modules of GeNWs are greater than that of bulk Ge. The thermal effect on mechanical properties of GeNWs are also investigated, and the pentagon GeNW exhibits the best mechanical properties among these three GeNWs. In the electronic properties, the electron density of state (DOS) of GeNWs was calculated by DFT to understand orbital hybridization. The result shows that the energy bands of GeNWs shift up to cross the Fermi-level and resulting in conducting nanowires due to the less Coulomb screening effect and quantum confinement from nanowire structure. In addition, the energy band of GeNWs will exhibit significant splitting if which orbital electrons suffer from large Coulomb interactions. For the adsorption and diffustion behavior of Li ion on GeNWs, the various of adsorption sites and which corresponding adsorption energy have been calculated. The absorption energy of Li ion absorption on GeNWs are more stable than that on graphit or graphene. The barrier and transition states of Li ion diffusion on GeNWs were studied by the nudged elastic band (NEB) method, and the results show that the diffusion barrier of Li ion on GeNWsare similar with other material of Li ion battery electrode. The Li ion diffusion on the surface of pentagon GeNW between H3 and H3 adsorption sites with the lowest barrier, which only around 0.526 eV.
