Cu0.35Ga1.65S2.65

Cu0.35Ga1.65S2.65 is a copper-gallium sulfide compound semiconductor with a cation-deficient chalcopyrite structure, representing a quaternary or complex ternary semiconductor system. This material is primarily of research and developmental interest for photovoltaic and optoelectronic applications, where its tunable bandgap and potential for efficient light absorption make it a candidate for thin-film solar cells and light-emitting devices. The incorporation of gallium and the specific copper deficiency create electronic properties distinct from binary or simpler ternary sulfides, offering opportunities to engineer device performance in next-generation semiconductor technologies.
