Strongly Anisotropic Spin and Orbital Rashba Effect at a Tellurium - Noble Metal Interface
B. Geldiyev, M. Ünzelmann, P. Eck +19
We study the interplay of lattice, spin and orbital degrees of freedom in a two-dimensional model system: a flat square lattice of Te atoms on a Au(100) surface. The atomic structu…
Field-induced ultrafast modulation of Rashba coupling at room temperature in ferroelectric -GeTe(111)
Geoffroy Kremer, Julian Maklar, Laurent Nicolaï +11
Rashba materials have appeared as an ideal playground for spin-to-charge conversion in prototype spintronics devices. Among them, -GeTe(111) is a non-centrosymmetric ferroelectr…
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…
Photoemission study on pristine and Ni-doped SrTiO thin films
F. Alarab, K. Hricovini, B. Leikert +12
We combined photoelemission spectroscopy with first-principle calculations to investigate structural and electronic properties of SrTiO doped with Ni impurities. In SrTiO$_{3…
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…
Bi monocrystal formation on InAs(111)A and B substrates
L. Nicolaï, J. -M. Mariot, U. Djukic +13
The growth of Bi films deposited on both A and B faces of InAs(111) has been investigated by low-energy electron diffraction, scanning tunneling microscopy, and photoelectron spect…
