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…

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…
