Tm4Sb2Se11.68
semiconductor· Tm4Sb2Se11.68
Tm4Sb2Se11.68 is a complex chalcogenide semiconductor compound combining thulium, antimony, and selenium in a layered crystal structure. This material belongs to the family of rare-earth chalcogenides, which are primarily investigated for thermoelectric and infrared optoelectronic applications due to their narrow bandgaps and phonon-scattering capabilities. While still in the research phase, such compounds are evaluated for mid-to-far infrared sensing, waste heat recovery systems, and solid-state cooling devices where traditional semiconductors reach performance limits.
