Abstract
Hall‐effect and solubility measurements are carried out on Cd‐doped PbTe crystals equilibrated with (Pb,Cd) alloys of various compositions at T=700 and 800 °C and quenched to room temperature. In Pb‐saturated conditions, while most of the Cd is found to be incorporated as neutral Cd on Pb sites CdxPb, a fraction of the total amount of Cd is present as positively charged interstitial species Cdi compensated by electrons. A complete defect model which can predict the behavior of Cd‐doped PbTe in Cd‐rich atmospheres as well as in Te‐rich atmospheres is proposed.This publication has 7 references indexed in Scilit:
