ZnCu2SnSe4
semiconductor· ZnCu2SnSe4
ZnCu₂SnSe₄ is a quaternary semiconductor compound belonging to the chalcogenide family, featuring a tetrahedrally coordinated crystal structure similar to diamond-cubic lattices. This material is primarily investigated in photovoltaic and thermoelectric research contexts, where its tunable band gap and reasonable thermal and mechanical stability make it a candidate for thin-film solar cells and waste-heat energy conversion devices. While not yet commercialized at scale, compounds in this family are valued as alternatives to toxic lead halides and rare-earth-dependent semiconductors, offering potential for earth-abundant, sustainable optoelectronic applications.
