ZnO nanowire UV photodetector with multiple channels
Abstract
Purpose
The purpose of this paper is to investigate the optoelectronic properties of the multichannel ZnO UV photodetectors.
Design/methodology/approach
ZnO nanowires were assembled by dielectrophoresis for the UV photodetectors. Different ZnO channels were adjusted by different alternating current voltages and investigated for UV optoelectronic properties.
Findings
The number of the ZnO channels increases with the enhancing alternating current voltage. Optimum performance of the UV photodetectors is obtained with more channels.
Originality/value
Dielectrophoresis is a promising method for controllable assembly of multichannel ZnO photodetectors. ZnO photodetectors with more channels demonstrate a good response to 380-nm UV light, which shows great potential application in UV photodetector.
