CuS31
metal· JVASP-132449· CuS31
CuS31 is a copper sulfide compound belonging to the chalcogenide material family, likely representing a specific stoichiometric or non-stoichiometric phase of the Cu-S system. This material composition suggests potential interest in semiconductor or photovoltaic applications, as copper sulfides have been investigated for thin-film solar cells, photocatalysis, and other electronic/optoelectronic functions. Compared to conventional silicon-based or cadmium-based alternatives, copper sulfide compounds offer earth-abundant elemental composition and tunable bandgap properties, though commercial deployment remains limited and most applications remain in research or early development stages.
