Abstract
Transparent films of aluminum doped zinc oxide were obtained by reactive sputtering employing metallic zinc and aluminum targets. The targets were coaxially superposed in a single magnetron, by using a center hollow aluminum plate. Two different hole radii in the aluminum target were employed trying to modify the aluminum content. Sputtering power was kept constant at 50 W and temperature was set to 300, 400 and 500 °C. Oxygen partial pressure was 20 and 40% in argon. Film transparencies up to 85% were obtained using this method. X-ray diffraction and Raman spectroscopy measurements were performed to monitor the crystalline structure of the films. Sample resistance was determined by current voltage measurements.
