Abstract

Rapid photon response is demonstrated for devices made using individual single-crystalline selenium nanobelts. The temperature dependence of the photocurrent has been studied between - 70 to 100 {ring operator}C. The best performance is at temperatures below 40 {ring operator}C. The response time to fluorescent light is as quick as 30 ms once tunes on, and the recovery time is as short as 50 ms when the light is off. This study demonstrates the potential application of Se nanobelts for building fast photon detectors.
