Figure 10From: Persistent Photoconductivity Studies in Nanostructured ZnO UV SensorsPhotoresponse plots for nanostructure ZnO UV sensor for 7.6 × 102 Torr and vacuum levels of 4 × 10−2and 8 × 10−2 Torr. Note the PPC trend when the oxygen pressure is reduced.Inset photocurrent decay time with O2pressureBack to article page
