제목 Effect of substrate temperature on the electrical, structural and optical properties of Ag doped ZnO thin films
초록 The effect of substrate temperature on the structural, electrical and optical properties of Ag doped ZnO (SZO) thin films were investigated. All of the films were deposited with targets of 2 wt.% of Ag2O content using an e-beam evaporator and the substrate temperature varied from room temperature to 250oC. All of the deposited films were annealed in a temperature range between 350 - 650°C for 5 h in air. As deposited SZO thin films showed p-type conductivity except a sample fabricated at room temperature, and the films fabricated at 150oC showed the highest hole concentration of 3.98×1019 cm-3. As deposited thin films were randomly oriented and intensities of peaks increased as the heat treatment temperature increased. The thin films deposited at 150oC showed the highest UV emission intensity.
