We present a fast method to create interstitial oxygen concentration maps from resistivity calibrated photoluminescence images prior to and after a heat treatment at 450 1C. The method utilizes the influence of thermal donors on the effective doping concentration of a sample. Although the determination of thermal donor concentrations from conductivity measurements is customary in literature, we found that implementation of a mobility model is necessary to determine accurate concentrations of… CONTINUE READING
