Abstract:
The semiconductor manufacturing sector plans to introduce III/V film structures (eg, gallium arsenide (GaAs), indium arsenide (InAs) onto silicon wafers due to their high electron mobility and low power consumption. Aqueous solutions generated during chemical and mechanical planarization of silicon wafers can contain a mixture of metal oxide nanoparticles (NPs) and soluble indium, gallium, and arsenic. In this work, the cytotoxicity induced by Ga- and In-based NPs (GaAs, InAs, Ga2O3, In2O3) and soluble III-V salts on human bronchial epithelial cells (16HBE14o-) was evaluated using a cell impedance real-time cell analysis (RTCA) system. The RTCA system provided inhibition data at different concentrations for multiple time points, for example, GaAs (25 mg/L) caused 60% inhibition after 8 hours of exposure and 100% growth inhibition after 24 hours. Direct testing of As(III) and As(V) demonstrated significant cytotoxicity with 50% growth inhibition concentrations after 16-hour exposure (IC50) of 2.4 and 4.5 mg/L, respectively. Cell signaling with rapid rise and decrease in signal was unique to arsenic cytotoxicity, a precursor of strong cytotoxicity over the longer term. In contrast with arsenic, soluble gallium(III) and indium(III) were less toxic. Whereas the oxide NPs caused low cytotoxicity, the arsenide compounds were highly inhibitory (IC50 of GaAs and InAs = 6.2 and 68 mg/L, respectively). Dissolution experiments over 7 days revealed that arsenic was fully leached from GaAs NPs, whereas only 10% of the arsenic was leached out of InAs NPs. These results indicate that the cytotoxicity of GaAs and InAs NPs is largely due to the dissolution of toxic arsenic species.

Abstract:
In this paper, the dc performance of a double gate Junctionless Tunnel Field Effect Transistor (DG-JLTFET) has been further enhanced with the implementation of double sided nonuniform Gaussian doping in the channel. The device has been simulated for different channel materials such as Si and various III-V compounds like Gallium Arsenide, Aluminium Indium Arsenide and Aluminium Indium Antimonide. It is shown that Gaussian doped channel Junctionless Tunnel Field Effect Transistor purveys higher ION/IOFF ratio, lower threshold voltage and sub-threshold slope and also offers better short channel performance as compared to JLTFET with uniformly doped channel.

Abstract:
Semiconducting lead halide perovskites (LHPs) have not only become prominent thin-film absorber materials in photovoltaics but have also proven to be disruptive in the field of colloidal semiconductor nanocrystals (NCs). The most important feature of LHP NCs is their so-called defect-tolerance—the apparently benign nature of structural defects, highly abundant in these compounds, with respect to optical and electronic properties. Here, we review the important differences that exist in the chemistry and physics of LHP NCs as compared with more conventional, tetrahedrally bonded, elemental, and binary semiconductor NCs (such as silicon, germanium, cadmium selenide, gallium arsenide, and indium phosphide). We survey the prospects of LHP NCs for optoelectronic applications such as in television displays, light-emitting devices, and solar cells, emphasizing the practical hurdles that remain to be overcome.

Abstract:
Planar optical-guided-wave devices have been in existence for over 20 years. Two interesting, informative articles can be found in References 1 and 2. Much of the early work in guided-wave optics was on passive devices, but this was also when much of the theoretical understanding of optical-guided-wave (OGW) devices was developed. This theoretical understanding applies to active devices as well. It's interesting to note that the commercialization of passive, glass-based guided-wave devices has just occurred with product introductions by Corning & Nippon Sheet Glass. Active OGW devices (i.e., ones where the light properties can be altered with an applied voltage) have been reported since about 1975. In 1985, Crystal Technology, Inc. announced the first commercially available product—a high-speed, efficient, intensity modulator. Throughout the ten years in between, a huge amount of technical literature has been generated. Most of the work has centered on the Ti:LiNbO3 waveguide technology although several other material systems have been demonstrated as well.Materials upon which optical-guided-wave modulators have been fabricated include: dielectrics such as lithium niobate (LiNbO3), lithium tantalate (LiTaO3), and potassium titanyl phosphate (KTP); the III-V semiconductor compounds, gallium arsenide (GaAs) and indium phosphide (InP); and a variety of organic polymers. Of these materials, waveguides on LiNbO3 are clearly the most developed and are offered for sale commercially. For this reason I will concentrate on this material system while making comparisons to the other material systems when appropriate.

Abstract:
A pulse-laser based time-resolved photocurrent (TRPC) and photoluminescence (TRPL) system with a programmable Boxcar integrator/averager system incorporated was implemented to investigate the optical properties and charge carrier dynamics in a GaInP/GaAs single-junction photovoltaic device for the purposes of understanding fundamental optoelectronic processes in the solar cell. The implementation of whole system was realized by integrating the instrument of a Boxcar averager system with a pulse laser source + spectroscopic facilities. The delay time control and data acquisition were organized by the software code. The effects of the hardware configurations and the software parameters on the performance of the system were particularly addressed for the optimization of measurement conditions and precisions. Two main functions of TRPC and TRPL with a wide time range were demonstrated for the system. The system was employed to measure temperature- and bias voltages-dependent TRPC and TRPL spectra of a GaInP/GaAs single-junction photovoltaic device. The spectral data show a lot of information about the transient dynamic behaviors of photogenerated charge carriers in the device, including both the rise and decay processes. Interestingly, the measured time-resolved photocurrent curves are characterized by a fast rising edge followed by a relatively slow decay process as the temperature increases. Relevant theoretical calculations and analysis to the experimental curves were also carried out to understand diffusion and transport processes of charge carriers inside the device. The results show that the variation in temperature and reverse biases results in the structural change in the space charge region of the P-N junction and therefore affects the rise and decay time constants of the time-resolved photocurrent. The TRPL spectral data give information of mid-way radiative recombination of charge carriers in the device.

Abstract:
This study focuses on the development of InAs/GaInSb strained-layer superlattice structures by metal organic chemical vapour deposition (MOCVD), and deals with two aspects of the development of InAs/GaInSb SLS’s by MOCVD viz. the deposition of nano-scale (~100 Å) GaInSb layers, and the electrical characterization of unstrained InAs. The first part of this work aims to study the MOCVD growth of GaInSb layers in terms of deposition rate and indium incorporation on the nano-scale. This task is approached by first optimizing the growth of relatively thick (~2 μm) epitaxial films, and then assuming similar growth parameters during nano-scale deposition. The GaInSb layers were grown as part of GaInSb/GaSb quantum well (QW) structures. By using this approach, the GaInSb QW’s (~100 Å) could be characterized with the use of photoluminescence spectroscopy, which, when used in conjunction with transmission electron microscopy and/or X-ray diffractomery, proves useful in the analysis of such small scale deposition. It is shown that the growth rate of GaInSb on the nano-scale approaches the nominal growth rates determined from thick (~2 μm) GaInSb calibration layers. The In incorporation efficiency in nano-layers, however, was markedly lower than what was predicted by the GaInSb calibration layers. This reduction in indium incorporation could be the result of the effects of strain on In incorporation. The choice of substrate orientation for QW deposition was also studied. QW structures were grown simultaneously on both (100) and 2°off (100) GaSb(Te) substrates, and it is shown that growth on non-vicinal substrates is more conducive to the deposition of high quality QW structures. The second part of this study focuses on the electrical characterization of unstrained InAs. It is long known that conventional Hall measurements cannot be used to accurately characterize InAs epitaxial layers, as a result of parallel conduction resulting from surface and/or interface effects. This study looks at extracting the surface and bulk electrical properties of n-type InAs thin films directly from variable magnetic field Hall measurements. For p-type InAs, the situation is complicated by the relatively large electron to hole mobility ratio of InAs which tends to conceal the p-type nature of InAs thin films from Hall measurements. Here, this effect is illustrated by way of theoretical simulation of Hall data.

Abstract:
The coupling between longitudinal-optical (LO) phonons and neutral excitons in two different kinds of InGaAs pyramidal quantum dots embedded in either AlGaAs or GaAs barriers is experimentally examined. We find a slightly weaker exciton-LO-phonon coupling and increased linewidth of the phonon replicas for the quantum dots with GaAs barriers compared to the ones with AlGaAs barriers. These results, combined with the fact that the LO-phonon energy of the exciton is the same for both kinds of dots, are taken as evidence that the excitons mainly couple to LO-phonons within the QDs.

Abstract:
Imaging technology has been in revolutionary progresses in decades with well-developed semiconductor and memory industries. Silicon sensors are used in most of camera and DV, since silicon is the best material for visible light imaging (wavelength from 400nm∼700nm). Short wave infrared (SWIR) requires indium gallium arsenide (InGaAs), composed of chemical compounds including indium arsenide (InAs) and gallium arsenide (GaAs), to cover SWIR spectrum. Wavelength of typical SWIR is defined between 0.7um and 2.5um; SWIR cameras focus on wavelength between 0.9um∼1.7um (In0.53Ga0.47As). Unlike Mid-Wave IR and Long-Wave IR, SWIR is reflected and absorbed by objects, which advantages SWIR imaging higher resolution due to better contrast. SWIR also has excellent imaging quality in low illumination environment and moon light or star light are good emitters outdoor at night. Another primary characteristic of SWIR is high penetration, providing effective imaging under hazy conditions. An Example for night vision between SWIR.
