Ratchet effect in lateral plasmonic crystal: Giant enhancement due to interference of "bright" and "dark" modes
I. V. Gorbenko, S. O. Potashin, V. Yu. Kachorovskii
We develop a theory of the ratchet effect in a lateral plasmonic crystal (LPC) formed by a two dimensional electron gas under a periodic dual-grating gate. The system is driven by…
Thermoelectric and viscous contributions to the hydrodynamic ratchet effect
S. O. Potashin, L. E. Golub, V. Yu. Kachorovskii
We study thermoelectric and viscous contributions to the ratchet effect, i.e. radiation-induced generation of the direct electric current, in asymmetric dual-grating…
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…
Beatings of ratchet current magneto-oscillations in GaN-based grating gate structures: manifestation of spin-orbit band splitting
P. Sai, S. O. Potashin, M. Szola +8
We report on the study of the magnetic ratchet effect in AlGaN/GaN heterostructures superimposed with lateral superlattice formed by dual-grating gate structure. We demonstrate tha…
Hydrodynamic Inverse Faraday Effect in Two Dimensional Electron Liquid
S. O. Potashin, V. Yu. Kachorovskii, M. S. Shur
We show that a small conducting object, such as a nanosphere or a nanoring, embedded into or placed in the vicinity of the two-dimensional electron liquid (2DEL) and subjected to a…
