Structure and transparent conductive properties of F-doped ZnO(FZO) thin films prepared by reactive magnetron sputtering
F-doped ZnO (FZO) films were prepared by reactive sputtering using Zn/ZnO/ZnF<sub>2</sub> mixture as the target at substrate temperature (<i>T</i><sub>s</sub>) of 150℃ and 300℃ and sputtering atmosphere of Ar+O<sub>2</sub> and Ar+H<sub>2</sub&...
