· JVASP-111382· Cd2GaCuSe4

Cd₂GaCuSe₄ is a quaternary semiconductor compound belonging to the I-III-II-VI family of semiconductors, combining cadmium, gallium, copper, and selenium in a crystalline structure. This material is primarily of research and development interest for optoelectronic and photovoltaic applications, where its tunable bandgap and compound semiconductor properties make it relevant for next-generation solar cells, photodetectors, and light-emitting devices. While not yet widely commercialized compared to binary or ternary semiconductors, materials in this chemical family are investigated as alternatives to conventional semiconductors due to their potential for improved absorption characteristics and device tunability in specialized applications.
