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…
