Cu3GeS4
metal· JVASP-155395· Cu3GeS4
Cu3GeS4 is a quaternary semiconductor compound belonging to the chalcogenide family, combining copper, germanium, and sulfur in a stoichiometric ratio. This material is primarily of research and developmental interest for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties offer potential advantages in solar cells, photodetectors, and infrared sensing devices. Cu3GeS4 represents an emerging alternative to more established semiconductors, with particular promise in thin-film photovoltaics and as a non-toxic replacement candidate in systems where lead or cadmium-based compounds have been traditionally used.
