Investigation on AZO Films Deposited by Radio-Frequency Reactive Magnetron Sputtering

The Al2O3-doped ZnO(AZO) films were deposited on the glasses by means of RF magnetron sputtering technology. The films were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Profile-system respectively. The effect of substrate temperature on the structure of the AZO films is investigated.As a result, the properties of the AZO thin films are remarkably influenced by the substrate temperature , especially in the range of 200°C to 500 °C. The film prepared at the substrate temperature of 400°C possesses the best crystalline.
