Defect structure of Znhyphen;doped PbTe

摘要

PbTe single crystals are equilibrated with (Pb,Zn) alloys of various compositions at 700 and 800thinsp;deg;C and quenched to room temperature. Hallhyphen;effect and solubility measurements of these crystals indicate that zinc acts as a donor in PbTe, being incorporated in interstitial sites as Znicompensated by electrons. A complete defect model for Znhyphen;doped PbTe is arrived at, which predicts the behavior of PbTe crystals in metalhyphen;rich as well as Tehyphen;rich atmospheres.
