Rhenium disulfide (ReS2) is best known as a 2D transition metal dichalcogenide. However, it could potentially also be used as a 1D material. Xianquan Meng, Wuhan University and Hubei Nuclear Solid Physics Key Laboratory, China, and colleagues have synthesized 1D single-crystal ReS2 nanowires using chemical vapor deposition (CVD).


The researchers used these nanowires as the active layer in a photodetector. To create the nanostructured photodetector, the team used conductive silver nanowires as the source and drain electrodes of the device and ReS2 nanowires as the active layer between these two contacts.


The nanowire-based photodetector has an excellent performance, with a high photoresistivity of 5.08·105, a high external quantum efficiency of 1.07·106, and the highest specific detectivity of ReS2 photodetectors to date, with a value of 6.1·1015.
