LiInSe2
semiconductor· LiInSe2
LiInSe2 is a ternary semiconductor compound composed of lithium, indium, and selenium, belonging to the chalcogenide semiconductor family. It is primarily investigated in research contexts for optoelectronic and photovoltaic applications, particularly where wide bandgap semiconductors with layered crystal structures are needed. The material's potential applications leverage its semiconductor properties for infrared detection, nonlinear optical devices, and emerging photovoltaic technologies, though it remains largely in the experimental phase compared to more mature semiconductor alternatives.
