ScTlSe2
semiconductor· ScTlSe2
ScTlSe2 is a ternary semiconductor compound combining scandium, thallium, and selenium in a layered chalcogenide structure. This material belongs to the family of mixed-metal selenides and is primarily of research interest for exploring novel electronic and optical properties in quantum materials rather than established commercial applications. The combination of heavy elements (Tl, Se) with early transition metals (Sc) positions it as a candidate for investigating topological behavior, nonlinear optical effects, or narrow-bandgap semiconductor applications in specialized photonic and optoelectronic devices.
