Unveiling the complete dispersion of the giant Rashba split surface states of ferroelectric α-GeTe(111) by alkali doping
α-GeTe(111) is a noncentrosymmetric ferroelectric material for which a strong spin-orbit interaction gives rise to giant Rashba split states in the bulk and at the surface. The detailed dispersions of the surface states inside the bulk band gap remains an open question because they are located in th...
