In this paper, Zinc Oxide nanorods with different thicknesses are grown on a glass substrate by a hydrothermal method to fabricate an ultraviolet photodetector. The sample is post annealed in an argon environment as an annealing process can have a positive effect on the photodetector performance. The morphology, crystalline structure, and optical properties of ZnO nanorods (NRs) are investigated by SEM, XRD, UV-Visible spectrometer, and PL spectra. The goal of this study is to investigate the effect of both growth time and post annealing on enhancement of photoresponse of the ZnO NR photodetector. Measurements indicate that the sample with higher thickness exhibits a higher photocurrent and photoresponsivity. Also, with post annealing, an increase in photocurrent and photoresponsivity is observed due to decreasing defect levels. [ABSTRACT FROM AUTHOR] |
