· JVASP-105814· MgAs

Magnesium arsenide (MgAs) is a binary ceramic compound belonging to the III-V semiconductor family, formed from magnesium and arsenic. It is primarily investigated as a research material for optoelectronic and semiconductor device applications, though it remains less commercially developed than competing III-V compounds like GaAs or InAs. MgAs is notable for its potential in wide-bandgap semiconductor applications and has attracted academic interest for high-temperature electronics and photonic devices, though practical industrial adoption has been limited due to synthesis challenges, thermal stability concerns, and competition from more established III-V materials.
