Tl1 Cd1 Te2
semiconductor· Tl1 Cd1 Te2
CdTe (cadmium telluride) is a II-VI compound semiconductor with a direct bandgap, commonly encountered in the form of polycrystalline thin films. It is primarily used in photovoltaic devices and radiation detection applications, where its high photon absorption coefficient and reasonable charge carrier mobility make it an attractive alternative to silicon for space and terrestrial solar panels, as well as X-ray and gamma-ray detectors. The material offers particular advantages in high-temperature and high-radiation environments, though cadmium toxicity and manufacturing complexity require careful handling and environmental controls compared to more conventional semiconductors.

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.
