Answer (1 of 10): This is a great question, thanks. GaAs didn't go away. It just didn't go into mainstream cheapo electronics, it stuck with the niches that silicon just can't function in. And those niches are quite plentiful even in consumer devices. Ultimately the argument in any large-scal...

In this monograph, IARC concluded that gallium arsenide is carcinogenic to humans (Group 1). The TLVs for hexafluoroacetone (male endpoint), nitrous oxide (developmental endpoint) and vinyl cyclohexene dioxide (male and endpoints) were assigned on the basis of ACGIH's findings of reproductive effects.
This monograph evaluates the evidence of carcinogenicity of metallic cobalt particles with or without tungsten carbide, to which workers in the hard-metal industry are exposed, and of cobalt sulfate and other soluble cobalt (II) salts. It also evaluates three other particulate compounds: gallium arsenide and indium phosphide, which are used extensively in the microelectronics industry; and ...
Gallium arsenide single crystals are more difficult to fabricate than those of silicon. With silicon, only one component needs to be controlled, whereas with gallium arsenide, a 1:1 ratio of gallium atoms to arsenic atoms must be maintained. At the same time, arsenic …
