EuCu2SnS4
semiconductor· EuCu2SnS4
EuCu₂SnS₄ is a quaternary sulfide semiconductor compound combining europium, copper, tin, and sulfur—a member of the I-II-IV-VI family of materials being investigated for photovoltaic and optoelectronic applications. This is primarily a research-stage material rather than an established commercial compound; it is studied for potential use in thin-film solar cells and light-emitting devices due to its tunable bandgap and earth-abundant constituent elements, offering a lower-cost and less-toxic alternative to traditional cadmium-based or lead halide semiconductors.
