BaNa2SnS4
semiconductor· BaNa2SnS4
BaNa₂SnS₄ is a quaternary sulfide semiconductor compound containing barium, sodium, and tin elements in a layered or framework crystal structure. This is a research-phase material primarily of interest for photovoltaic and optoelectronic applications, where its bandgap and sulfide chemistry position it as a potential alternative to more conventional semiconductors like CdTe or perovskites. The material belongs to the broader family of metal sulfide semiconductors, which are studied for thin-film solar cells, photodetectors, and light-emitting devices where earth-abundant or less-toxic compositions are desired compared to cadmium or lead-based alternatives.
