Terahertz spin ratchet effect in magnetic metamaterials
M. Hild, L. E. Golub, A. Fuhrmann +10
We report on spin ratchet currents driven by terahertz radiation electric fields in a Co/Pt magnetic metamaterial formed by triangle-shaped holes forming an antidots lattice and su…
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…
Terahertz photogalvanics in twisted bilayer graphene close to the second magic angle
M. Otteneder, S. Hubmann, X. Lu +6
We report on the observation of photogalvanic effects in twisted bilayer graphene (tBLG) with a twist angle of 0.6°. We show that excitation of tBLG bulk causes a photocurrent, who…
Terahertz Magnetospectroscopy of Cyclotron Resonances from Topological Surface States in Thick Films of CdHgTe
M. Otteneder, D. Sacré, I. Yahniuk +10
We present studies of the cyclotron resonance (CR) in thick CdHgTe films with different cadmium concentrations corresponding to inverted and normal band order, as well…
