Synthesis of NbSe2 single-crystalline nanosheet arrays for UV photodetectors

Abstract

High-quality single-crystalline NbSe2 nanosheet arrays were successfully synthesized by a salt and hydrogen co-assisted CVD method, and the crystal structure and morphology of the material were investigated by XRD, Raman spectroscopy and TEM/HRTEM. The metallic electrical transport properties of the materials were validated by experimental measurement and DFT computation. The NbSe2 nanosheet array photodetectors showed very high responsivity and external quantum efficiency to UV light.
