· Te4 Mo4 Se2 S2

Te₄Mo₄Se₂S₂ is a mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, selenium, and sulfur in a layered structure. This material belongs to the family of transition metal chalcogenides, which are of significant research interest for optoelectronic and energy conversion applications due to their tunable bandgaps and strong light-matter interactions. While primarily an experimental compound, such quaternary chalcogenides are being investigated for next-generation photovoltaics, photodetectors, and thermoelectric devices where conventional binary or ternary semiconductors reach performance limits.
