· ZnTe

Zinc telluride (ZnTe) is a II-VI compound semiconductor with a zinc blende crystal structure, notable for its wide direct bandgap and strong nonlinear optical properties. It is primarily used in optoelectronic and photonic applications, particularly for infrared detectors, electroluminescent devices, and as a substrate or buffer layer in heterostructure devices operating in the visible-to-infrared spectrum. Engineers select ZnTe when direct bandgap semiconductors are required for efficient light emission or detection, or when lattice matching with other compound semiconductors is critical for quantum well and superlattice device designs.

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.
