Impurity-pinned incommensurate charge density wave and local phonon excitations in 2H-NbS2

Chenhaoping Wen, Yuan Xie, Yueshen Wu +6

Here we report a scanning tunneling microscopy (STM) and spectroscopy (STS) study in the superconducting state of 2H-NbS2. We directly visualize the existence of incommensurate cha…
