GALLIUM ARSENIDE: STRUCTURE, PROPERTIES, USES,

Structure. Gallium arsenide has a 1: 1 ratio between an element of Group III of the periodic table and an element of Group V, which is why it is called compound III-V. It is considered to be an intermetallic solid composed of arsenic (As) and gallium (Ga) with oxidation states ranging from Ga (0) Ace (0) up to Ga (+3) Ace (-3). Nomenclature

Gallium Arsenide an overview ScienceDirect Topics

Gallium arsenide (GaAs) as a MEMS substrate is a brittle, difficult- to-process material [7] and the machining of GaAs, by diamond saw or by conventional laser, releases arsenic into the atmosphere.This is in the form of either dust or as arsine gas. The LMJ, however, contains the Arsenic within the water, which can be filtered out and disposed of in an environmentally controlled manner [7, 8].
