Doped zinc oxide thin films for photodetectors devices

Abstract

In this work, structural, electrical properties of Li doped ZnO thin films, by chemical pulverization grown on glass substrates at different Li doping concentrations, were reported. Besides, The effects of lithium doping on structural properties of ZnO: Li thin films were studied by means of XRD technique. This study demonstrated that all prepared thin films consisted of unique phase ZnO and were well crystallized in wurtzite structure with the preferentially orientation (002) in the direction parallel to c-axis. The obtained results showed that these films have polycrystalline wurtzite-structure and high c-axis preferred orientation. Besides, the ZnO photodetectors revealed superior performance in the view of photocurrent.
