Abstract

The photoresponse characteristics of ZnO films prepared by unbalanced magnetron sputtering were discussed. The changes in the crystallographic orientation and the microstructure of the film were also presented. It was found that the magnitude of the photocurrent and the rise time decreased with increasing number of trap levels.
