Conduction Band Structure and Ultrafast Dynamics of Ferroelectric $\alpha$-GeTe(111)

Geoffroy Kremer, Laurent Nicolaï, Frédéric Chassot +9

$\alpha$-GeTe(111) is a non-centrosymmetric ferroelectric (FE) material for which a significative lattice distortion combined with a strong spin-orbit interaction gives rise to giant Ra…
