Influence of Oxygen-Argon Ratio on ZrO2 Thin Films Deposited on Transparent Conductive ITO Substrates

Article Preview

Abstract:

This study investigated the correlation between the oxygen-argon ratio and crystal phase, the surface flatness and electrical properties of ZrO2 thin films The films were deposited on transparent conductive indium tin oxide (ITO) substrates by DC magnetron sputtering. ZrO2 films exhibit ZrO cubic and ZrO2 monoclinic mixed phases when deposited with a low oxygen-argon ratio of 5:45. As the oxygen-argon ratio increases, a gradual phase transition ZrO to orthorhombic ZrO2 occurs. Besides, the ZrO2 film deposited with an oxygen-argon ratio of 10:40 exhibits highest resistance to electric field strength, and lowest leakage current.
