摘要

We studied the electrical properties of Cd0.9Zn0.1Te:In (CZT) single crystals with [In]=3*1015 at/cm3 at its high-temperature point-defect (PD) equilibrium state under a Cd overpressure (PCd). We detailed the influence of thermal treatment and the deviation of stoichiometry on the electron concentration, observing unexpectedly high conductivity and an increase in free-electron density ( ~ 1.5-2 or...
