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…
