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

14 Jun 2020 Wen Chenhaoping Xie Yuan Wu Yueshen Shen Shiwei Kong Pengfei Lian Hailong Li Jun Xing Hui Yan Shichao

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 charge density wave (CDW) that is pinned by atomic impurities... (read more)
