Abstract

The authors introduce the sol-gel technique to grow the ZrO2 and ZrO2:polyvinyl alcohol (PVA) composite thin films. For ZrO2 and ZrO2:PVA thin films, the photoluminescence and field emission scanning electron microscopy results are compared, indicating that the ZrO2 agglomeration process is effectively controlled by incorporating PVA, which results in the removal of crystallographic defects. In order to determine the correlation between morphology and performance, the Au/ZrO2/n-type Si (n-Si) and Au/ZrO2:PVA/n-Si devices are fabricated and their current-voltage characteristics are obtained. The electrical conduction investigations suggest that the substrate-injection leakage behavior is governed by the space-charge-limited current (thermionic emission-diffusion) for Au/ZrO2/n-Si (Au/ZrO2:PVA/n-Si) devices. The incorporation of PVA into ZrO2 is an important issue for modulating the leakage performance of Au/ZrO2/n-Si devices.
