· Al2 Te2 I14

Al₂Te₂I₁₄ is an experimental mixed-halide semiconductor compound combining aluminum, tellurium, and iodine—a member of the halide perovskite and post-perovskite material families under active research. This composition falls within the emerging class of layered and 3D halide semiconductors being explored for optoelectronic devices, where compositional tuning (particularly through iodine substitution) offers control over bandgap and carrier transport properties. While not yet a commercial material, compounds in this family are of interest to researchers developing next-generation photovoltaic absorbers, scintillators, and X-ray detectors where the heavy elements (tellurium and iodine) provide strong light absorption and radiation stopping power.

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.
