Current-induced enhancement of photo-response in graphene THz radiation detectors
K. Indykiewicz, C. Bray, C. Consejo +4
Thermoelectric readout in a graphene THz radiation detector requires a p-n junction across the graphene channel. Even without an intentional p-n junction, two latent junctions can…
Temperature Dependent Zero-Field Splittings in Graphene
C. Bray, K. Maussang, C. Consejo +15
Graphene is a quantum spin Hall insulator with a 45 eV wide non-trivial topological gap induced by the intrinsic spin-orbit coupling. Even though this zero-field spin splitting…
Demonstration of high sensitivity of microwave-induced resistance oscillations to circular polarization
M. L. Savchenko, A. Shuvaev, I. A. Dmitriev +3
We demonstrate that long-debated immunity of microwave-induced resistance oscillations (MIRO) to the sense of circular polarization is not a generic property of this phenomenon in…
Circular polarization immunity of the cyclotron resonance photoconductivity in two-dimensional electron systems
Erwin Mönch, Philipp Euringer, Georg-Maximilian Hüttner +7
Studying the cyclotron resonance (CR)-induced photoconductivity in GaAs and HgTe two-dimensional electron structures, we observed an anomalous photoresponse for the CR-inactive geo…
THz ratchet effect in HgTe interdigitated structures
I. Yahniuk, G. V. Budkin, A. Kazakov +9
The emergence of ratchet effects in two-dimensional materials is strongly correlated with the introduction of asymmetry into the system. In general, dual-grating-gate structures fo…
THz radiation induced circular Hall effect in graphene
S. Candussio, S. Bernreuter, T. Rockinger +6
We report on the observation of the circular transversal terahertz photoconductivity in monolayer graphene supplied by a back gate. The photoconductivity response is caused by the…
