This solid is a semiconductor material with a direct band gap of 2.26 eV.〔 It is usually a p-type semiconductor. Its crystal structure is cubic, like that for sphalerite and diamond.〔 ==Properties== ZnTe has the appearance of grey or brownish-red powder, or ruby-red crystals when refined by sublimation. Zinc telluride typically had a cubic (sphalerite, or "zincblende") crystal structure, but can be also prepared as hexagonal crystals (wurzite structure). Irradiated by a strong optical beam burns in presence of oxygen. Its lattice constant is 0.6101 nm, allowing it to be grown with or on aluminium antimonide, gallium antimonide, indium arsenide, and lead selenide. With some lattice mismatch, it can also be grown on other substrates such as GaAs,〔O'Dell, Dakota (2010). (MBE Growth and Characterization of ZnTe and Nitrogen-doped ZnTe on GaAs(100) Substrates ), Department of Physics, University of Notre Dame.〕 and it can be grown in thin-film polycrystalline (or nanocrystalline) form on substrates such as glass, for example, in the manufacture of thin-film solar cells. In the wurtzite (hexagonal) crystal structure, it has lattice parameters a = 0.427 and c = 0.699 nm.〔Kittel, C.
