Terahertz field-driven nonlinear Hall effect and other second order transport phenomena in two-dimensional tellurene
M. D. Moldavskaya, L. E. Golub, E. Mönch +4
We study terahertz field-driven second-order nonlinear electron transport phenomena, including the nonlinear Hall effect (NLHE), in two-dimensional tellurene flakes. The dc current…
Strongly nonlinear Bernstein modes in graphene reveal plasmon-enhanced near-field magnetoabsorption
I. Yahniuk, I. A. Dmitriev, A. L. Shilov +12
Bernstein modes -- hybrid magnetoplasmon excitations arising from the coupling between cyclotron motion and collective oscillations in two-dimensional electron systems -- offer dir…
Terahertz radiation driven nonlinear transport phenomena in two-dimensional tellurene
Erwin Mönch, Mariya D. Moldavskaya, Leonid E. Golub +7
Nonlinear electron transport induced by polarized terahertz radiation is studied in two-dimensional tellurene at room temperature. A direct current, quadratic in the radiation's el…
Terahertz and gigahertz magneto-ratchets in graphene-based 2D metamaterials
Marcel Hild, Erwin Mönch, Leonid E. Golub +15
We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene mono…
Nonlinear helicity anomalies in the cyclotron resonance photoresistance of two-dimensional electron systems
Erwin Mönch, Sophia Schweiss, Ivan Yahniuk +7
Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incom…
Nonlinear intensity dependence of ratchet currents induced by terahertz laser radiation in bilayer graphene with asymmetric periodic grating gates
Erwin Mönch, Stefan Hubmann, Ivan Yahniuk +9
We report on the observation of a nonlinear intensity dependence of the terahertz radiation induced ratchet effects in bilayer graphene with asymmetric dual grating gate lateral la…
Cyclotron- and magnetoplasmon resonances in bilayer graphene ratchets
Erwin Mönch, Sergey O. Potashin, Katja Lindner +10
We report on a tunable - by magnetic field and gate voltage - conversion of terahertz radiation into a dc current in spatially modulated bilayer graphene. We experimentally demonst…
Ratchet effect in spatially modulated bilayer graphene: Signature of hydrodynamic transport
Erwin Mönch, Sergey O. Potashin, Katja Lindner +10
We report on the observation of the ratchet effect -- generation of direct electric current in response to external terahertz (THz) radiation -- in bilayer graphene, where inversio…
Highly superlinear photogalvanic effects in (BiSb)(TeSe): Probing 3D topological insulator surface states at room temperature
Sergey N. Danilov, Leonid E. Golub, Thomas Mayer +8
We report on the observation of complex nonlinear intensity dependence of the circular and linear photogalvanic currents induced by infrared radiation in compensated (BiSb$…
