· AsSeI

AsSeI is a ternary chalcogenide semiconductor compound combining arsenic, selenium, and iodine. This material belongs to the family of mixed-halide and mixed-chalcogenide semiconductors, which are primarily of research interest for optoelectronic and photovoltaic applications. AsSeI and related compounds are investigated for potential use in thin-film solar cells, infrared detectors, and nonlinear optical devices, where the tunable bandgap and layered crystal structure offer advantages over more conventional semiconductors, though commercial deployment remains limited.

Export Control

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.
