Unveiling the complete dispersion of the giant Rashba split surface states of ferroelectric -GeTe(111) by alkali doping
G. Kremer, T. Jaouen, B. Salzmann +9
-GeTe(111) is a non-centrosymmetric ferroelectric material, for which a strong spin-orbit interaction gives rise to giant Rashba split states in the bulk and at the surface. The…
