· Br18 Te2 Ta2

Br₁₈Te₂Ta₂ is an experimental mixed-halide semiconductor compound combining bromine, tellurium, and tantalum in a layered or complex crystal structure. This material belongs to an emerging class of multinary semiconductors being investigated for optoelectronic and solid-state device applications where tunable bandgaps and mixed-cation/anion chemistry offer advantages over binary or ternary alternatives. While not yet commercialized, compounds of this type are of interest in photovoltaics, photodetectors, and radiation detection due to the heavy-element content (tantalum) and halide stability, though synthesis and reproducibility remain active research challenges.

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.
