Measuring anisotropic spin relaxation in graphene
Sebastian Ringer, Stefan Hartl, Matthias Rosenauer +5
We compare different methods to measure the anisotropy of the spin-lifetime in graphene. In addition to out-of-plane rotation of the ferromagnetic electrodes and oblique spin prece…
Terahertz electric field driven electric currents and ratchet effects in graphene
Sergey D. Ganichev, Dieter Weiss, Jonathan Eroms
Terahertz field induced photocurrents in graphene were studied experimentally and by microscopic modeling. Currents were generated by cw and pulsed laser radiation in large area as…
Circular and linear magnetic quantum ratchet effects in dual-grating-gate CdTe-based nanostructures
P. Faltermeier, G. V. Budkin, S. Hubmann +9
We report on the observation and systematic study of polarization sensitive magnetic quantum ratchet effects induced by alternating electric fields in the terahertz frequency range…
Ballistic geometric resistance resonances in a single surface of a topological insulator
Hubert Maier, Johannes Ziegler, Ralf Fischer +5
Transport in topological matter has shown a variety of novel phenomena over the last decade. Although numerous transport studies have been conducted on three-dimensional topologica…
Probing Spin Helical Surface States in Topological HgTe Nanowires
Johannes Ziegler, Raphael Kozlovsky, Cosimo Gorini +10
Nanowires with helical surface states represent key prerequisites for observing and exploiting phase-coherent topological conductance phenomena, such as spin-momentum locked quantu…
Magneto-resistance oscillations induced by high-intensity terahertz radiation
T. Herrmann, Z. D. Kvon, I. A. Dmitriev +12
We report on observation of pronounced terahertz radiation-induced magneto-resistivity oscillations in AlGaAs/GaAs two-dimensional electron systems, the THz analog of the microwave…
