Broadband MoS2 Square Nanotube-Based Photodetectors
Source abstract
Abstract
Although the research on layered MoS 2 photodetectors has made great progress, their poor light absorption ability and complex preparation process hinder their further commercial application. In the present work, we report the growth of MoS 2 square nanotubes with high purity via a facile hydrothermal method for the first time. Microstructure characterization demonstrates that the cavity structure of the nanotubes can bring about a light trapping effect, thus obtaining a strong photoelectric performance. The as-constructed MoS 2 square nanotube photodetector with a paper substrate displays a broadband response with a detection range of 375 to 915 nm. It exhibits excellent performance with a high responsivity of 2.33 mA/W under 915 nm light irradiation, which is comparable to the best ones ever reported for polycrystalline MoS 2 photodetectors.
