Fabrication of photoswitch device based on zinc oxide nanorods
Abstract
The application of zinc oxide nanorods (ZnO-NRs) as photo-switch was presented in this paper. The effect of varying sample lengths on the performance of the device was also reported. The growth of ZnO-NRs was confirmed through scanning electron microscopy (SEM). The I-V characteristics and photo-switch response of the samples were characterized using a programmable I-V curve tracer and multimeter, respectively. The non-illuminated and illuminated I-V curves of the samples have shown an increase in the photo-response upon increasing the length of the sample. The photo-switch testing of all the samples have given a fast response.
