Abstract

In this paper, vertically aligned Ga-doped ZnO nanorods are grown on glass substrate by a low-temperature process, hydrothermal method. The Ga-doped ZnO nanorods are needlelike in shape. The field-emission performance can be enhanced by Ga dopant and needlelike in shape. It is found that the turn-on electrical field is reduced from 3.63 to 3.15 Vμ m and the field enhancement factor is enhanced from 9058 to 13529 by ultraviolet (UV) illumination. Under UV illumination, the Ga-ZnO nanorods photodetectors exhibit a high UV photocurrent fast rise time, and high UV-to-visible ratio.
