· In4 Te4

In₄Te₄ is a narrow-bandgap semiconductor compound belonging to the III-VI family, composed of indium and tellurium in a 1:1 stoichiometric ratio. This material is primarily of research and developmental interest for thermoelectric applications and infrared optoelectronics, where its thermal and electrical transport properties are being evaluated as an alternative to more established telluride semiconductors. Engineers considering In₄Te₄ would be exploring next-generation thermoelectric devices for waste heat recovery or specialized infrared detectors, though it remains less mature than established materials in these markets.

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.
