▼ Over the past 35 years, much effort has gone into the development of semiconductor nanostructures. A key application is to use quantum states, e.g. electron or hole spins, for information processing. This thesis investigates the underpinning physics of spin-orbit interactions in nanostructures, which could be used for fast spin-state operation, and electron-hole recombination in ambipolar devices, which could be used to convert spin states to photon polarizations.Initially, we report on the spin-orbit interaction induced electron g-factor anisotropy in InAs nanowire quantum dots. The quantum dot structure is defined by random potential fluctuations along the nanowire. By fine-tuning the gate bias, we can resolve regular Coulomb diamonds, characteristic of a single quantum dot. By monitoring the Coulomb peak spacing for different magnetic field orientation, we mapped the anisotropy of the electron g-factor.The following two chapters investigate heavy holes in silicon quantum dots for high fidelity spin state operation. The strong spin-orbit interaction of heavy holes promises high-speed spin rotations with purely electrical signals. The silicon host crystal could minimize the effect of hyperfine interactions. Based on a versatile multi-layer gate metal-oxide-semiconductor (MOS) structure, we could define a stable single hole transistor operating from the many hole regime down to the few hole regime.Furthermore, we used the flexibility of the MOS structure to also define a double quantum dot system. We report the first observation of Pauli spin blockade of heavy holes, which is used to convert spin states to electric charges. By mapping the transport current under different magnetic field, and inter-dot energy detuning, we could identify the leading spin relaxation mechanism, and how it depends on the inter-dot tunnel coupling. The results obtained here are important milestones for realizing hole spin quantum bits.Finally, we investigate the possibility of spin state telecommunication with photons. We demonstrate radiative recombination of electrons and holes in a GaAs ambipolar field-effect transistor of a similar design used to make quantum dots. The device structure uses two top gates for independent electron and hole density control, allowing a p-i-n junction to be formed without doping. By tuning the top gates bias, we could shift the recombination zone to the unperturbed intrinsic region, allowing high light-emission efficiency.

Resumo: Neste trabalho foram estudadas as propriedades foto e eletroluminescentes de dois polímeros conjugados derivados de polifluorenos, o Poli[(9,9-dioctil-fluorenil-2,7-diil)¿terminado com fenila dimetilada (PFO) e o Poli[(9,9-dioctilfluorenil-2,7-diil)-alt-co-(1,4-benzo-{2,1¿,3}-tiadiazol) (F8BT). Os diodos emissores de luz (LED) desses dois materiais foram montados de acordo com a configuração ITO/PEDOT:PSS/PVK/Camada ativa/Ca/Al e caracterizados em função da escala de cromaticidade CIE do espectro de eletroluminescência, luminância, densidade de corrente em função da tensão e eficiência de corrente.O estudo fotofísico foi realizado utilizando-se a camada ativa dos mesmos dispositivos. . O LED de PFO apresentou a escala de cromaticidade x = 0,16, y = 0,11 e de F8BT x = 0,34, y = 0,64, cujas cores de emissão são azul e verde, respectivamente. Em seguida, estudou-se a possibilidade de utilização de filmes de álcool polivinílico (PVA) contendo corantes xantênicos (rosa de bengala, eosina B e eritrosina B) como camada de conversão de cor (CCL) para tais dispositivos. Foi possível apenas modificar a cor do dispositivo de F8BT, uma vez que não há absorção de luz pelos corantes na região de emissão do PFO. Os resultados mais expressivos foram observados com a utilização rosa de Bengala, apresentando maior mudança na escala de cromaticidade e também maior redução da luminância para o F8BT. Além dos dispositivos supracitados, na tentativa de se obter uma escala de cromaticidade mais próxima da branca (x=0,33; y=0,33), dispositivos de configuração semelhante aos anteriores foram montados trocando-se a camada ativa por blendas ou bicamadas de F8BT e PFO, com diversas composições. A partir da modulação de cor através da CCL de PVA contendo rosa de bengala obteve-se um deslocamento da escala de cromaticidade para o azul nesses dispositivos, uma aproximação da cor branca e uma significativa redução da luminância. Os melhores resultados foram obtidos com o dispositivo de blenda contendo 2% de F8BT/ 98% PFO, que partiu da escala de cor (x=0,30;y=0,49) para (x=0,29;y=0,42) com uma camada externa de PVA:Rosa de bengala (0,044mm) e a menor redução da luminância (71%)

In this work was studied the photo and eletroluminescent properties of two conjugated polyfluorene derivative polymers, Poly[9,9-dioctylfluorenyl-2,7-diyl] ¿ end capped with DMP (PFO) and the Poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(1,4-benzo-{2,1¿,3}-thiadiazole)] (F8BT). Light-emitting diodes were prepared according to the configuration ITO/PEDOT:PSS/PVK/Active Layer/Ca/Al and the eletroluminescence, CIE chromaticity coordinates, luminance, current density-tension curves and current efficiency-tension curves were…

▼ In this study, we used Suzuki coupling to synthesize TPSBF, BNASBF, and TNASBF blue emitter featuring four identical strongly emitting pyrene and anthracene units linked around a stable spirobifluorene core. This fluorine derivative exhibits a high fluorescence yield, extreme thermal stability under N2 (three compounds exhibit distinct decomposition temperatures higher than 470â), a high glass transition temperature (ca. 240 Â°C of TPSBF), and a stable deep blue emission in the solid state. The presence of the spiro linkage in the structure was active to the emitting behavior of the monomeric units. In addition, the tetrahedral nature of the carbon atom at the spiro center preserves the optical and electrochemical characteristics of the pristine pyrene and anthracene units. we describe how the morphology, photoluminescence (PL), and electroluminescence properties of 2,2Â´,7,7Â´-tetrakis(pyren-1-yl)-9,9Â´-spirobifluorene (TPSBF) are related to its film thickness and how, under optimized conditions, its three main PL emissions constitute a form of white light. We fabricated high-brightness, broad-spectrum, white-light organic light-emitting diodes incorporating a single emission layer of the blue light-emitting material TPSBF.

▼ This paper tries to explore the phosphor optical characteristics through reliability tests using white light emitting diodes (WLEDs) with a high color rendering index (CRI ,Raï¼90). Based on light mixing principles and considering the high CRI, three color-coded powders were mixed separately with silicone into a phosphor, and then bottomed with blue chips into WLEDs. The three powders were oxide nitride (red), YAG (yellow), and silicate (green). Two kinds of samples were fabricated â phosphor and emitters similar to commercial products. Both cool-white (CCT=5650~7000K, lumen efficiencyï¼60 lum/w.) and warm-white (CCT=2850~3250K, lumen efficiencyï¼50 lum/w.) samples passed the Bin Code distribution process and brightness measurement. The results indicate better lumen efficiency than previously published research. After the three kinds of mono-colored phosphors were created, .we implemented the reliability test in which three CREE standards were chosen. These standards were (1) high temperature with high humidity test (60â , 90% humidity) in operating and non-operating condition; (2) thermal shock test (-40â ~125â ); (3) life time test. The thermal shock test showed the decaying power of intensity for red, yellow, and green phosphors were 11.7%, 17.5%, and 19.3% respectively. These results demonstrate that the red phosphor has the best thermal resistance. However, after the high temperature with high humidity tests, the decaying power of intensity for red,yellow, and green phosphor were 15.7%, 10.1% and 6.4% correspondingly. These results show that the green phosphor has best aqua resistance. In the life time test of emitters, the decaying power of intensity for the cool-white emitter was 3.2%, while the warm-white emitter showed 4.2%. As such, cool-white emitters were concluded to have better reliability than warm-white emitters.

▼ Deep ultraviolet (UV) light sources are useful in a number of applications that include sterilization, medical diagnostics, as well as chemical and biological identification. However, state-of-the-art deep UV light-emitting diodes and lasers made from semiconductors still suffer from low external quantum efficiency and low output powers. These limitations make them costly and ineffective in a wide range of applications. Deep UV sources such as lasers that currently exist are prohibitively bulky, complicated, and expensive. This is typically because they are constituted of an assemblage of two to three other lasers in tandem to facilitate sequential harmonic generation that ultimately results in the desired deep UV wavelength. For semiconductor-based deep UV sources, the most challenging difficulty has been finding ways to optimally dope the (Al,Ga)N/GaN heterostructures essential for UV-C light sources. It has proven to be very difficult to achieve high free carrier concentrations and low resistivities in high-aluminum-containing III-nitrides. As a result, p-type doped aluminum-free III-nitrides are employed as the p-type contact layers in UV light-emitting diode structures. However, because of impedance-mismatch issues, light extraction from the device and consequently the overall external quantum efficiency is drastically reduced. This problem is compounded with high losses and low gain when one tries to make UV nitride lasers. In this thesis, we provide a robust and reproducible approach to resolving most of these challenges. By using a liquid-metal-enabled growth mode in a plasma-assisted molecular beam epitaxy process, we show that highly-doped aluminum containing III-nitride films can be achieved. This growth mode is driven by kinetics. Using this approach, we have been able to achieve extremely high p-type and n-type doping in (Al,Ga)N films with high aluminum content. By incorporating a very high density of Mg atoms in (Al,Ga)N films, we have been able to show, by temperature-dependent photoluminescence, that the activation energy of the acceptors is substantially lower, thus allowing a higher hole concentration than usual to be available for conduction. It is believed that the lower activation energy is a result of an impurity band tail induced by the high Mg concentration. The successful p-type doping of high aluminum-content (Al,Ga)N has allowed us to demonstrate operation of deep ultraviolet LEDs emitting at 274 nm. This achievement paves the way for making lasers that emit in the UV-C region of the spectrum. In this thesis, we performed preliminary work on using our structures to make UV-C lasers based on photonic crystal nanocavity structures. The nanocavity laser structures show that the threshold optical pumping power necessary to reach lasing is much lower than in conventional edge-emitting lasers. Furthermore, the photonic crystal nanocavity structure has a small mode volume and does not need mirrors for optical feedback. These advantages significantly reduce material loss and eliminate mirror loss.…

▼ This thesis is concerned with the preparation of organic light-emitting diodes (LEDs) by using different thin film technologies: the Langmuir-Blodgett (LB) technique; spin-coating and thermal evaporation. The π-conjugated polymer, poly(2-methoxy-5-(5'-ethylhexyloxy)-p-phenylenevinylene) (MEH-PPV), was used as the emissive layer and was deposited onto patterned indium-tin oxide (ITO) glass using the LB technique or spin-coating. Y-type LB films of MEH-PPV were deposited at a surface pressure of 17 mN m(^-1) with a transfer ratio of 0.95 ± 0.03. Many efforts were made to improve the LB film device performance parameters, such as external quantum efficiency and operating lifetime, by inserting an electron transporting or insulating layer between the emissive layer and top cathode. Annealing the LB films was found to result in an improved operating lifetime. LEDs based on spun films possessed higher external quantum efficiencies than devices made from LB films. The more ordered LB films had a higher probability of intra- and intermolecular interactions and formed more excimer states within the structure. This led to a lower quantum efficiency compared to devices incorporating spun films. The operating lifetime of the LEDs was highly dependent on the morphology of the film surface. A smoother film surface is required for a longer device operating lifetime. A new electron transporting material, 2,5-bis[2-(4-tert-butylphenyl)-1,3,4-oxadiazol-5-yl]pyridine (PDPyDP), was deposited on top of the MEH-PPV spun film. Despite a high external quantum efficiency of 0.7 %, this device suffered from dark regions in the electroluminescence output resulting in degradation of the device. The dark area formation was attributed to delamination of the aluminium electrode from the PDPyDP layer, which was lessened by: (a) annealing the degraded devices; (b) evaporating a thicker aluminium layer at a high rate and (c) inserting a buffer layer (Alq(_3)) between the PDPyDP and the Al top electrode.

▼ Hybrid halide perovskites have emerged as competitive semiconducting materials for optoelectronic devices due to their superior optoelectronic properties and low cost processability. Current perovskite solar cell efficiency fabricated in lab is 24.2% which is approaching towards the maximum theoretical limit of 30.14% in a fast pace. However, commercialization ventures of this technology are experiencing some key challenges. Production scalability, operational stability in various extreme environment, and toxicity of the materials are three main concerns. Attempt to scale up the solar cells for large panels cannot retain the high efficiency as in lab scale. One of the main reasons behind this limitation is inability to deposit high quality active perovskite film on large area substrates. The conventional approach to create high quality films from solution is to introduce additional arrangement or increasing process steps. These solutions result in impressive film quality, however are unsuitable for large scale film deposition. In this dissertation, an optimum ink formulation was developed for methylammonium lead iodide (MAPI) perovskite instead of increasing process steps to improve film quality. An additive named methylammonium acetate (MAAc) was introduced to the precursor solution at different ratio to retard the reaction kinetics by forming an intermediate phase. The processing parameters were determined for high quality film deposition. Films derived from different MAAc precursor ratios were characterized using SEM, XRD, XPS, UV-Vis, PL, and ellipsometry. Finally, solar cells and light emitting diodes were fabricated to evaluate the perovskite films in functioning devices. Further, the performance and operational stability of the MAPI solar cell devices were investigated under wide range of temperature and illumination intensities to interrogate the performance in various extreme conditions. The temperature range (40 – 430 K) covers two phase transition points of perovskite. Recombination of generated carriers is one of the foremost loss mechanisms in the solar cell. The combined intensity dependent short circuit density (JSC) and open circuit voltage (VOC) analysis were exploited for a recombination study. The mixture of bimolecular and trap-assisted recombination was observed in the devices. MAPI films are soluble in most of the polar organic solvents and thus until now they were not considered suitable for electrochemical processing. In this work, we report on hydrofluroether (HFE) solvent-based electrolyte for electrochemical processing and characterization of perovskite thin films. The results obtained here show that chemically orthogonal electrolytes based on HFE solvents do not dissolve organic perovskite films and thus allow electrochemical characterization of the electronic structure, investigation of charge transport properties and potential electrochemical doping of the films with in-situ diagnostic capabilities.

▼ The greenhouse industry is interested in light emitting diodes (LEDs) as a light source supplement to solar light to improve plant growth and development. Before LEDs can be adopted as supplemental light for greenhouse crops, plant responses to LED spectral quality need to be investigated. Tomato and cucumber seedlings were grown under different supplemental blue and red photon flux ratios (B:R ratios) under high (16-19 mol m⁻² d⁻¹) and low (5-9 mol m⁻² d⁻¹) solar daily light integrals (DLIs). The supplemental daily light integral was 3.6 mol m⁻² d⁻¹. A treatment without supplemental light served as a control. Both tomato and cucumber seedlings had increased growth rate and improved morphology when grown under the supplemental LED light compared to the control. However, no significant differences were observed for any growth and morphological parameters measured in this study between the different B:R ratios for both cucumber and tomato transplants under high DLI conditions. Cucumber seedlings showed a tendency to decrease dry mass, leaf number and leaf area under low DLI conditions with increasing B:R ratio. Tomato seedlings did not show any differences between the different B:R ratios under low DLI conditions. Seedlings growth and morphology under supplemental LED light were compared to those under supplemental high pressure sodium (HPS) light. Cucumber seedlings under supplemental HPS light had greater shoot dry mass than those under the supplemental red LED light. Tomato shoot dry mass showed no differences between the HPS and red LED supplemental light treatments. Cucumber seedlings were also grown under supplemental LED pulsed lighting and supplemental LED continuous lighting. Cucumber seedlings showed no differences in shoot dry mass and net photosynthetic rate between the treatments. Collectively, these studies concluded that red LED is preferred for supplemental lighting and the increase of blue light does not offer any benefits unless the efficiency of blue LEDs largely exceeds the red LEDs. The results of this research can be used for fixture development by LED manufactures and as a decision making tool for the adoption of supplemental LED lighting by greenhouse growers.
