GALLIUM ARSENIDE 1. Exposure Data

The monitoring of occupational exposure to gallium arsenide can only be based on measurements of arsenic or gallium concentrations in workplace air or in human tissues or body fluids (biological monitoring), because there is no analytical method capable of measuring gallium arsenide per se in the above media.

US Patent for Multi-layer gallium arsenide-based fresnel

A new nonlinear optical structure for frequency conversion is described. The new nonlinear optical structure is a multilayer wafer comprising alternating layers of gallium arsenide and aluminum gallium arsenide onto a gallium arsenide substrate. The new device is both more efficient and easier to make than prior art gallium arsenide crystal structures designed for nonlinear optical conversion.

Challenge of Applying Ohmic Contacts to Gallium

Ohmic Contacts to Gallium Arsenide This introduces the problem of making ohmic electrical contacts to gallium arsenide (GaAs) devices. Formation of ohmic contacts to compound semiconductors is considerably more difficult than with silicon or germanium due to the reactivity of their constituents and inter-diffusion with the metal.

Graphene/gallium arsenide-based Schottky junction solar

Chemical-vapor-deposited single- and bi-layer graphene sheets have been transferred onto n-type GaAs substrates. The rectifying characteristics and photovoltaic behaviors of graphene/GaAs junctions have been systematically investigated. The graphene sheets can be combined with the underlying n-type GaAs substrates to form Schottky junctions.

Plasma Chemical Etching of Gallium Arsenide in C2F5Cl

Abstract. The plasma chemical etching of gallium arsenide in chloropentafluoroethane (C 2 F 5 Cl) inductively coupled plasma is for the first time performed taking into account surface passivation by products of reagent decomposition. The elemental composition of deposited layers, their density, and morphological properties are studied.
