· GdTe

Gadolinium telluride (GdTe) is a rare-earth compound semiconductor belonging to the lanthanide chalcogenide family, formed from gadolinium and tellurium. While primarily a research material rather than a commercial product, GdTe and related rare-earth tellurides are investigated for potential applications in infrared optics, thermoelectric devices, and specialized semiconductor research due to the unique electronic and optical properties imparted by gadolinium's f-electron structure. Engineers encounter GdTe in exploratory work on narrow-bandgap semiconductors and materials for cryogenic or extreme-environment sensing where rare-earth dopants or compounds offer advantages over conventional III-V or II-VI semiconductors.

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.
