· Cu3YbS3

Cu3YbS3 is a ternary semiconductor compound combining copper, ytterbium, and sulfur, belonging to the family of metal chalcogenides with potential for optoelectronic and thermoelectric applications. This material is primarily of research interest rather than established in commercial production; it is being investigated for its semiconducting properties and potential use in photovoltaic devices, thermal energy conversion, and quantum materials research where the rare-earth ytterbium dopant provides distinctive electronic characteristics distinct from binary copper sulfides.
