CsCu2SbS3
semiconductor· CsCu2SbS3
CsCu₂SbS₃ is a quaternary chalcogenide semiconductor compound combining cesium, copper, antimony, and sulfur in a layered or complex crystal structure. This material is primarily of research and development interest rather than established industrial production, belonging to the family of copper-based sulfide semiconductors with potential for photovoltaic and thermoelectric applications. Its appeal lies in earth-abundant constituent elements and tunable optoelectronic properties compared to toxic or rare-earth-dependent alternatives, though it remains in the early evaluation phase for commercial viability.
