Observation of antiphase coherent phonons in the warped Dirac cone of BiTe
E. Golias, J. Sánchez-Barriga
In this Rapid Communication we investigate the coupling between excited electrons and phonons in the highly anisotropic electronic structure of the prototypical topological insulat…
Ultrafast spin polarization control of Dirac fermions in topological insulators
J. Sánchez-Barriga, E. Golias, A. Varykhalov +7
Three-dimensional topological insulators (TIs) are characterized by spin-polarized Dirac-cone surface states that are protected from backscattering by time-reversal symmetry. Contr…
Magnetically induced spin reorientation on the surface of a topological insulator (a surface magnetic topological insulator MBE film)
Su-Yang Xu, M. Neupane, Chang Liu +18
The surface of topological insulators is proposed as a promising platform for spintronics and quantum information applications. In particular, when time- reversal symmetry is broke…
Topological surface state under graphene for two-dimensional spintronics in air
A. Varykhalov, D. Marchenko, M. R. Scholz +3
Spin currents which allow for a dissipationless transport of information can be generated by electric fields in semiconductor heterostructures in the presence of a Rashba-type spin…
