Triple point fermions in ferroelectric GeTe
Juraj Krempaský, Laurent Nicolaï, Martin Gmitra +10
Ferroelectric GeTe is unveiled to exhibit an intriguing multiple non-trivial topology of the electronic band structure due to the existence of triple-point and type-II Weyl fermion…
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…
Surface versus bulk contributions to the giant Rashba splitting in the ferroelectric α-GeTe(111) semiconductor
J. Krempaský, H. Volfová, S. Muff +14
In systems with broken inversion symmetry spin-orbit coupling (SOC) yields a Rashba-type spin splitting of electronic states, manifested in a k-dependent splitting of the bands. Wh…
