Gd(CuS)3

Gd(CuS)₃ is a ternary semiconductor compound combining gadolinium, copper, and sulfur, belonging to the family of rare-earth transition-metal chalcogenides. This material is primarily of research and developmental interest for optoelectronic and thermoelectric applications, where the combination of rare-earth and copper-sulfide chemistry offers potential for tunable bandgap, magnetic properties, and charge-carrier behavior. Its use in commercial applications remains limited; the material is explored in academic and specialized laboratory settings as a candidate for next-generation photovoltaic devices, photodetectors, and materials with coupled electronic-magnetic functionality.
