LiGaS2
semiconductor· LiGaS2
LiGaS2 is a ternary III-V semiconductor compound combining lithium, gallium, and sulfur, belonging to the family of wide-bandgap semiconductors used for optoelectronic and photonic applications. The material is primarily investigated in research contexts for infrared (IR) optics, nonlinear optical devices, and potentially high-voltage electronic applications due to its wide bandgap and strong nonlinear optical properties. LiGaS2 is notable for its potential in mid-to-far infrared windows where traditional semiconductors like GaAs become transparent, making it valuable for specialized optical systems and frequency conversion devices in defense, sensing, and spectroscopy industries.
