Mg3As2
semiconductor· Mg3As2
Mg3As2 is an III–V compound semiconductor formed from magnesium and arsenic, belonging to the family of wide-bandgap materials investigated for optoelectronic and high-temperature device applications. While primarily a research material rather than a commercial standard, it is explored for its potential in ultraviolet and visible light emission, as well as in high-power electronics where thermal stability and wide bandgap characteristics offer advantages over conventional semiconductors like silicon or gallium arsenide.
