High-field transport in gallium arsenide and indium
HighTfield transport in GaAs and InP 1643. gallium arsenide. an electron in the valley must have an energy in excess of 0.36 eV for. the transition to the X valleys to be possible, and its wavefunction then has a lower sym-. metry than at the r point, in particular having a strong admixture of p-symmetry.

Gallium Arsenides - an overview ScienceDirect Topics
G.3 Gallium arsenide. Gallium arsenide is another semiconductor material that is extensively used as a detection medium. The distinguishing feature of GaAs is its higher photon absorption efficiency as compared to silicon, which has allowed the development of extremely thin (100–200 μm) X-ray detectors. Another advantage of GaAs is that it can be operated at room temperature, which simplifies detector

A study on the extraction of gallium from gallium
The extraction of gallium from a GaAs scrap with various acids at different stirring speeds, temperatures, and concentrations of acids has been investigated. From these experiments, nitric acid was found to be the most effective extractant. More than 99% of gallium was leached with 2 N HNO3 at 60°C in 2 h, and the extraction of gallium was ...

Monte Carlo determination of electron transport
A Monte Carlo technique has been used to calculate the electron distribution functions in the (000) and (100) valleys of gallium arsenide. This method avoids having to make any of the conventional approximations used to solve the Boltzmann transport equation, but instead evaluates the distribution function exactly once the scattering rates have been specified.
