Giant ratchet magneto-photocurrent in graphene lateral superlattices
S. Hubmann, V. V. Bel'kov, L. E. Golub +5
We report on the observation of the magnetic quantum ratchet effect in graphene with a lateral dual-grating top gate (DGG) superlattice. We show that the THz ratchet current exhibi…

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…

High frequency impact ionization and nonlinearity of photocurrent induced by intense terahertz radiation in HgTe-based quantum well structures
S. Hubmann, G. V. Budkin, A. P. Dmitriev +10
We report on a strong nonlinear behavior of the photogalvanics and photoconductivity under excitation of HgTe quantum wells (QWs) by intense terahertz (THz) radiation. The increasi…
