- 摘要：
- Vertically aligned TiO2 nanorods arrays were successfully synthesized on FTO glass by wet-chemical method. Based on polystyrene sulfate (PSS) functionalized TiO2 nanorods arrays, a sandwich-structured hybrid UV photodetector was fabricated. The photo-to-dark current ratio of the device increases by more than 3 orders of magnitude with typical case, while the dark current is about 10 nA at 1 V bias. The high photoresponse together with the low dark current could probably contribute a large photocurrent and low-power application. The high performance of the hybrid material and facile low-cost fabrication of the UV detector make the devices promising for large-area UV photodetection applications.
