Beryllium telluride

Chemical compound

Beryllium telluride (BeTe) is a chemical compound of beryllium and tellurium. It is a crystalline solid with the lattice constant of 0.5615 nm. It is a semiconductor with a large energy gap of around 3 eV. Toxicity is unknown. Toxic hydrogen telluride gas is evolved on exposure to water.
