Reversal of spin-polarization near the fermi level of the rashba semiconductor bitecl

HIGHLIGHTS

• who: J. Qu from the Published in partnership with Nanjing University have published the research: Reversal of spin-polarization near the Fermi level of the Rashba semiconductor BiTeCl, in the Journal: (JOURNAL) of 14/09/2022
• what: The authors show that this behavior follows from higher-order corrections to the canonical Rashba Hamiltonian, and based on arguments exploiting the crystal symmetry of BiTeCl, the authors conclude that the states are localized to individual trilayers. The authors focus on the Te-terminated surface, since its surface sub-band at the deepest binding_energy has been identified as . . .
