有鉴于此,近日,北京理工大学刘立巍副教授等利用扫描隧道显微镜/光谱学研究单层1T-NbSe2来阐明莫特上层哈伯德能带(UHB)的能量,并揭示出自旋极化的UHB在空间上的分布远离CDW单元中心的dz2轨道。此外,除了通常观察到的CDW图案外,UHB还显示出√3×√3R30°周期性。此外,在莫特间隙深处可以看到类似于CDW有序的图案,显示...
CDW pattern. Furthermore, a pattern similar to the CDW order is visible deep in the Mott gap, exhibiting CDW without contribution of the Mott Hubbard band. Based on these findings in monolayer 1T-NbSe2, we provide novel insights into the relation between the correlated and collective electronic...
Here we term a monolayer consisting of this structural unit 2H-NbSe2. Among TMDs, bulk 2H-NbSe2 has been the target of intensive studies, because it exhibits a unique ground state in which an incommensurate charge density wave (CDW) and superconductivity coexist below 7 K.10 Recent success ...

77Se NMR spectra of single-crystalline 2H-NbSe2 and 1T-VSe2 have been measured in the temperature range 7-295 K. For both compounds the NMR lineshape is strongly affected by the phase transition to the charge density wave (CDW) state at T0=31 K and 110 K, respectively. The temperature...

Quasi two-dimensional (2D) transition metal dichalcogenides metals like 1T/2H-TaSe2, 1T/2H-TaS2, 2H-NbSe2 are some of the materials that exhibit strong CDW distortions. While CDW can be directly probed using Scanning Tunnelling Microscopy (STM), diffraction and imaging techniques such as High ...
