NbSe2We have made scanning tunnelling microscope (STM) studies of the lattice expansion and topography of cleaved crystals of 2H-NbSe2 which were intercalated in situ with silver ions entering along one edge of the samples. The measurements confirm the high surface mobility of silver seen in ...

However, the latter dominates the STM tunneling conductance. Here we measure DOS in magnetic fields parallel to the surface and perpendicular to the $c$ axis. We find patterns of stripes due to in-plane vortex cores running nearly parallel to the surface. The patterns change with the in-...

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...
Scanning tunneling microscopy (STM) experiments have observed a transition from a 3Q CDW order on the surface to a 1Q charge stripe order near its edges, and the presence of impurities leads to a nontrivial dependence of superconducting transition temperature on impurity concentration. First-...
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 ...
