GaAs – A Compound Semiconductor Gallium arsenide is a compound semiconductor which may be defined as a semiconductor made of a compound of two elements (as opposed to silicon, which is a single element semiconductor). GaAs is the chemical symbols for gallium arsenide. Definition of Intrinsic Semiconductor. The range of integrated circuits (ICs) and wafer uses is extremely diverse. "Semi-insulating GaAs" is more-or-less synonymous with "GaAs with very few electrons or holes". It has very few electrons and holes because it has very few (effective) dopant atoms, not because it has a bigger bandgap than other GaAs.
