Fig. 1: Surface electronic structure of BiTeCl.
From: Reversal of spin-polarization near the Fermi level of the Rashba semiconductor BiTeCl
a Crystal structure and schematic of the bands localized near the Te-terminated surface due to a depth-dependent potential V(z). Each sub-band shows a Rashba-like spin splitting. b, c Spin-integrated ARPES measurements of the Te-terminated surface along Γ-K and Γ-M, respectively, revealing the sub-band structure.
