· TeI

Tellurium iodide (TeI) is an inorganic semiconductor compound combining tellurium and iodine elements. This material belongs to the chalcohalide family and is primarily of research and developmental interest rather than established high-volume industrial production. TeI is investigated for optoelectronic and photovoltaic applications where its semiconductor bandgap and light-absorption properties could enable next-generation detectors, infrared sensors, and thin-film solar cells, though practical engineering adoption remains limited compared to more mature semiconductors like silicon or gallium arsenide.

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.
