摘要：

NbSe2 is a typical transition metal dichalcogenide with a rich variety of electronic ground states existing in its nanostructures, including two-dimensional superconductivity and charge density wave. However, the direct growth of high-quality single-crystalline NbSe2 nanostructures is still challenging, which limits their applications in electronic devices. Here, we report the growth of high-quality NbSe2 nanoplates by a single-step chemical vapour deposition. Their temperature and magnetic-field dependent superconducting behaviors were investigated by four-terminal devices fabricated on individual nanostructures. The NbSe2 nanoplates show two-dimensional characteristics of superconducting transitions and strong anisotropy with magnetic field orientation, providing potential platforms for the exploration of new physics in nanoelectronic devices.
