2017年8月30日 · Atomic-resolution scanning transmission electron microscope imaging reveals the atomic structure of the intrinsic point defects and grain boundaries in monolayer NbSe 2, and confirms the low...

2024年10月1日 · Additionally, the observation of Shubnikov-de Haas (SdH) oscillations in NbSe2 is presented. At high–pressure in the absence of CDW order, high frequencies corresponding to a large Fermi surface of NbSe2 are observed for the first time, with DFT calculations providing some insight into their origin.

2016年9月16日 · We perform scanning tunneling microscopy simulations and find that the images noticeably change with the sign and magnitude of the voltage bias. The atomic corrugation of …

2015年10月13日 · The electronic transport properties of two-dimensional (2D) niobium diselenide (NbSe2) layer materials with two-hexagonal single-crystalline structures grown by chemical vapor transport were investigated. Those NbSe2 nanostructures isolated simply using mechanical exfoliation were found to exhibit lower cond

2018年6月15日 · In this work, we present a detailed ab initio calculation of the 2H- NbSe2 and \ (Fe {1/4}NbSe_ {2}\) for structural, electronic, and magnetic properties using a full potential linear -augmented plane wave (FP-LAPW) method within the WIEN2k code [34].

2015年7月20日 · Enhanced electron–phonon interactions in mono- and few-layer NbSe2 result in a significantly increased transition temperature of charge density waves compared with values in the bulk.

Here we demonstrate the experimental realization of superconductivity in a chemical vapour deposition grown monolayer material—NbSe2. Atomic-resolution scanning transmission electron microscope imaging reveals the atomic structure of the intrinsic point defects and grain boundaries in monolayer NbSe2, and con rms the low defect.

NbSe2材料减薄到单层极限时，可以获得二维Ising超导性，虽然面内上临界场显著提升，但超导转变温度却有所下降，仅有0.9-3.7K，也就是说单层NbSe2 Ising超导性的获得是以牺牲其他重要性质为代价的。

1994年6月13日 · A self-consistent band structure calculation, performed for 2H-NbSe 2 in the normal non-charge-density-wave state using a full potential linearized augmented plane wave (FLAPW) method, accounts well for the experimental angular dependence of the quantum oscillations in terms of a small flat hole Fermi surface around the Gamma point.

2003年5月1日 · Scanning tunneling microscopy/spectroscopy and resistivity (ρ) measurements were performed on NbSe 2 single crystals in which superconductivity and charge-density wave (CDW) coexist.
