Effects of Annealing Treatmenton on ZnO Nonowires Used for Utraviotet Detector
ZnO nanowires were assembled on Au interdigital electrodes by dielectrophoresis method and fabricated the nanowires UV detector. In order to assemble the ZnO nanowires on interdigital electrodes
the long ZnO nanowires were grown three times by hydrothermal method. Then
the ZnO nanowires was annealed under 700 ℃
which increased the availability of the surface defects. The photoresponse current ratio and recovery time of the UV detector fabricated with the annealed ZnO nanowires were significantly improved. The possible mechanism was studied by the photoluminescence and photoresponse spectra.
