Description
PbTe
PbTe crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice. It is a narrow gap semiconductor with a band gap of 0.32 eV. PbTe crystals are single crystalline grown by Bridgman technique to ensure high structural quality and thermoelectric and electronic performance.
