LiIn2CuSe4

LiIn2CuSe4 is a quaternary compound semiconductor belonging to the I-III-II-VI family of materials, combining lithium, indium, copper, and selenium in a structured lattice. This is primarily a research and development material studied for potential applications in optoelectronics, photovoltaics, and solid-state device applications, rather than an established industrial commodity. The material's interest stems from its semiconductor properties and the possibility of tunable electronic band gaps through composition variation, making it a candidate for next-generation solar cells, photodetectors, and thermoelectric devices where conventional binary or ternary semiconductors have limitations.
