Laser-ARPES As a complementary approach, we have performed high-resolution laser-ARPES to search for signatures of EPC on the low-energy electronic band dispersions of 2M-WS2, as illustrated in Fig.3a. The Fermi surface mapping measurement on the natural cleaved (100) surface (Fig.3b) shows ...
To investigate the overall electronic structure of 2M-WS2, we first carried out synchrotron-based ARPES measurements, and Fig.2bshows a typical set of experimental band structure, containing rich details that can be successfully reproduced by ab initio calculations (see Fig.2cand Supplementary Fig.4...
In this study, we present systematic investigations using Raman scattering and angle-resolved photoemission spectroscopy (ARPES) to examine the phononic and electronic subsystems of the topological superconductor candidate 2M-WS 2 . Raman scattering exhibits an anomalous nonmonotonic temperature dependence ...
