UV photosensors based on individual semiconductor nanowires

摘要

We present a functional photo sensing device based on individual metal oxide nanowires with a cost-effective interfacing electronics for computer controlled operation. The photoconductive gain and the dynamic response of the device were improved by optimizing the layout and depositing surface passivation coatings. Photoconductive gains of 6.10 4 and response times below 5s were obtained with the optimized prototypes.
