(1)CDW不仅仅能够在K点附近的内能带发生能带的打开,同时还可以在外能带发生打开。 (2)因此导致两个能带在空间上形成电子的异相电荷调制效果,而且通过STM成像的能量CDW对比度得以验证存在。 参考文献 Pásztor, Á., Scarfato, A., Spera, M. et al. Multiband charge density wave exposed in a transition ...

Our STM data are analyzed in light of other recent experiments which have probed the multiband features of this material. Our analysis suggests that the appearance of sub-gap spectral peaks and their non-trivial field evolution are distinct signatures of a second superconducting gap, and are ...
measured the vortex lattice of 2H-NbSe2 with STM in tilted magnetic fields14,15. They focused on the structure of the vortex lattice and found a distortion of the hexagonal lattice compatible with the anisotropy of the upper critical field, as well as a rotation of the orientation of the ...
NbSe2SUMMARY We have made scanning tunnelling microscope (STM) studies of the lattice expansion and topography of cleaved crystals of 2H-NbSe 2 which were intercalated in situ with silver ions entering along one edge of the samples. The measurements confirm the high surface mobility of silver ...

We present a scanning tunneling microscopy (STM) and ab-initio study of the anisotropic superconductivity of 2H-NbSe2 in the charge-density-wave (CDW) phase. Differential-conductance spectra show a clear double-peak structure, which is well reproduced by density functional theory simulations enabling...
STMBulk and single-layer 2H-NbSe2 exhibit identical charge density wave order (CDW) with a quasi-commensurate 3 x 3 superlattice periodicity. Here we combine scanning tunnelling microscopy (STM) imaging at T = 1 K of 2H-NbSe2 with first-principles density functional theory (DFT) calculations ...
