· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
