摘要: Ga/Al doped ZnO (GAZO) thin films were prepared on non-alkali glass substrate by co-sputtering system using two DC cathodes equipped with AZO (:2.0 wt%) target and GZO (:6.65 target. This study examined the influence of Al/Ga concentration temperature electrical, structural optical properties GAZO films. The lowest resistivity was obtained at room temperature. With increasing temperature, film decreased to a minimum value below . Furthermore, when 0.05% gas introduced, All had preferred orientation along (002) direction, indicating that deposited have hexagonal wurtzite structure formed textured growth c-axis. average transmittance more than 85% in visible light range.
