· TeI4

TeI₄ (tellurium tetraiodide) is an inorganic semiconductor compound composed of tellurium and iodine. It belongs to the class of halide semiconductors and is primarily of research and specialized application interest rather than a high-volume industrial material. The compound is investigated for optoelectronic and radiation detection applications where its bandgap and halide composition offer potential advantages in photon detection, though it remains less mature than established alternatives like CdTe or silicon detectors.

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.
