Ga-doped ZnO(ZGO) films are deposited by using DC magnetron sputtering with facing zinc oxide targets at room temperature in argon atmosphere.The crystal structure of the ZGO films is hexagonal wurtzite,and the orientation is along the c-axis perpendicular to the substrate.Textured ZGO films are prepared by etching the smooth films in 0.5% diluted HCl.The reflectivity of textured film in the visible range is decreased by 10% comparing with that of the smooth ZGO film,while the conductivity remains constant....
