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 ...
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 ...

The atomic image of 2H-NbSe2 surface was successfully recorded with a scanning tunneling microscope (STM) at room temperature. The trigonal pattern of the image is in good agreement with the results of the X-ray diffraction experiments. The STM apparatus developed here showed resolutions of 0.3 ...
Theoretical predictions of unconventional charge density waves (CDW) such as pair density waves have a characteristic symmetry of the energy dependence of the local density of state (LDOS) modulations. The scanning tunneling microscopy (STM) and spectroscopy (STS) techniques obtain information related ...

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 ...
