Abstract

Abstract: This study reports that photodetectors based on double‐layer ZnO nanorods grown on AZO seed layer by hydrothermal method. Compared with the photodetectors with single‐layer nanorods, the on/off ratio of the photodetectors with double‐layer ZnO nanorods is increased by ∼2.52 times, the photoresponsivity is increased ∼5.50 times, the sensitivity is increased ∼3.34 times and the response time was shortened by 0.97 and 6.65 s, respectively. Furthermore, the photocurrent derivative also shows that the photodetectors based on double‐layer ZnO nanorods has a faster response speed.
