· JVASP-17432· Cu2SnHgSe4

Cu2SnHgSe4 is a quaternary compound semiconductor combining copper, tin, mercury, and selenium elements. This material belongs to the family of mercury-containing chalcogenides, which are primarily of research interest for optoelectronic and thermoelectric applications rather than established industrial use. The inclusion of mercury presents significant handling and environmental considerations, limiting practical deployment compared to mercury-free alternatives, though the material's band structure and transport properties are investigated for specialized photonic and solid-state device research.
