· In4 Se4

In₄Se₄ is a ternary indium selenide compound belonging to the family of III-VI semiconductors, where indium and selenium form a layered or cluster-based crystal structure. This material is primarily of research and development interest for optoelectronic and thermoelectric applications, as the III-VI semiconductor family offers tunable bandgaps and promising charge-carrier properties for devices operating in the infrared to visible spectrum range. Engineers may consider In₄Se₄ and related indium selenides when designing next-generation photodetectors, light-emitting devices, or thermal energy conversion systems where conventional materials like GaAs or CdTe face limitations in cost, toxicity, or spectral performance.

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.
