| Popis: | 104 In this study, the lower cost Au-nano particles(Au-NPs) has been obtained by chemical reduction and inserted the Al-doped Zinc Oxide (AZO) layer to enhance the optoelectronic properties. At first the improved AZO thin film had been treated as seed layer, and then the Au-NPs were dropped on the etched surface of seed layer, the proper treatment as thermal and spin had been done before the deposition of AZO capping layer, and then the AZO/Au-NPs/AZO thin film was finished. The scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscope (AFM) were used to analysis the structure and distribution of Au nano particles, and the crystalline intensity of AZO thin film. The optoelectronic properties were measured by Hall-effect measurement and UV-VIS-NIR Spectrophotometer system. The result shown the optimum optoelectronic properties of AZO/Au-NPs/AZO thin film was measured after 700℃、20min thermal sintering, 500rpm spin speed and 500℃、10min thermal annealing. The resistance reduces to 3.77×10-2Ω-cm, the average transmittance in visible increases to 85.63%, and the optimum figure of merit is 4.50×10-5Ω-1. |
