For the production of indium arsenide whiskers to be stable under high-energy electron irradiation, the mathematical model describing the deposition of tin-doped indium arsenide whiskers from vapor phase was created. Presented mathematical model covers the issues related to the analysis of the g...

The impact of uni-axial compressive and tensile strain and diameter on the electronic band structure of indium arsenide (InAs) nanowires (NWs) is investigated using first principles calculations. Effective masses and band gaps are extracted from the electronic structure for relaxed and strained ...

Deflection of carriers by Lorentz force results in an ordinary magnetoresistance (OMR) of (μB)2 at low field. Here we demonstrate that the OMR in high mobility semiconductor InAs could be enhanced by measurement geometry where two probes of voltmeter were both placed on one outer side of two pr...

Gallium arsenide is an important semiconductor material marketed in the shape of wafers and thus is not hazardous to the end user. Exposure to GaAs particles may, however, occur during manufacture and processing. Potential hazards require evaluation. In 14-week inhalation studies with small GaAs...

In this article, a computational study on the photovoltaic performance and electrical characteristics of graphene/gallium arsenide Schottky junction solar cell with structure graphene/SiO2/GaAs/Au is undertaken. Graphene is used as a transparent current conducting electrode. Design and simulatio...

Gallium arsenide (GaAs) is a material widely used in electronic devices. Disposal of electronic waste containing GaAs in municipal solid waste landfills raises concerns about the public health and ecological risks associated with the potential release of toxic arsenic (As) species. In this study...

Here we investigate recombination in polytype gallium arsenide (GaAs) nanowires (NWs) for photovoltaic applications, through photoluminescence studies coupled with rate equation analysis. Polytype NWs exhibit switching between zinc-blende (ZB) and wurtzite (WZ) crystal phases along the wire due ...

Gallium (Ga), in the form of gallium arsenide (GaAs) has been extensively used as a substrate in semiconductor materials. The use of microorganisms is fast becoming a promising alternative to not only leach the metal at low concentrations, but to do so in a more safe, environmental friendly as w...

Porous mullite and mullite-alumina composites have been developed from China clay and aluminium fluoride trihydrate (AlF3·3H2O) with various amounts of Al2O3. China clay undergoes a moisture aided vapour phase reaction with AlF3·3H2O during sintering, forming a porous mullite network having ne...

Low cost, single-phase porous cordierite ceramics are successfully synthesized by in-situ solid-state reactions from fly ash, quartz, and magnesite.

The cordierite is one of the most important phases within the MgO-Al2O3-SiO2 (MAS) system. In this study, the crystallization and microstructure of cordierite was analyzed. Four samples were prepared, which were subjected to a thermal treatment at a temperature of 1200 °C with a permanence time...

Sandy soils cover large proportions of Australia’s cereal-cropping region and are wide-spread globally. Sandy soils often have low organic C (OC) content due to limited plant growth and rapid decomposition because of low clay concentration. The addition of subsoil clay to sandy soil has the pot...

Water-based drilling muds, a more environment-friendly candidate than oil-based drilling muds, are wildly used for drilling oil and gas wells. When water-based drilling mud is used for drilling formations with shale containing active clay constituents, it is challenging to preserve stability of ...
