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.
