Observation of terahertz-induced magnetooscillations in graphene
Erwin Mönch, Denis A. Bandurin, Ivan A. Dmitriev +6
When high-frequency radiation is incident upon graphene subjected to a perpendicular magnetic field, graphene absorbs incident photons by allowing transitions between nearest LLs t…
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…
Symmetry breaking and circular photogalvanic effect in epitaxial CdHgTe films
S. Hubmann, G. V. Budkin, M. Otteneder +13
We report on the observation of symmetry breaking and the circular photogalvanic effect in CdHgTe alloys. We demonstrate that irradiation of bulk epitaxial films with c…
Perspectives of HgTe Topological Insulators for Quantum Hall Metrology
Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16
We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one , corresponding to the topological phase transition and graphen…
