metal

· JVASP-100835· GaCuSe2

GaCuSe2 is a ternary chalcogenide compound combining gallium, copper, and selenium in a fixed stoichiometry. This is primarily a research and experimental material studied for its potential semiconducting and optoelectronic properties rather than an established industrial workhorse. The material belongs to the family of I-III-VI2 semiconductors, which are explored for photovoltaic devices, photodetectors, and nonlinear optical applications where conventional binary semiconductors have limitations.
