a, b STM images of monolayer WSe2 and Td-MoTe2, respectively. c LEED pattern of monolayer Td-MoTe2. d, e Band structure of monolayer WSe2. d Original ARPES band structure of monolayer WSe2 (hv = 21.2 eV) along Γ-K high symmetry line. The valence band maximum (VBM) is positioned at K instead of Γ, which is an important signature of monolayer WSe2. e Second-derivative spectra of band dispersion along K–M–K’, showing clear spin-orbital coupling (SOC) induced spin-splitting bands.
