Electron spin resonance driven photogalvanic effect in graphene-based structures
C. Bray, I. Yahniuk, L. E. Golub +13
We report an electron-spin-resonance-driven linear photogalvanic effect (LPGE) in unbiased monolayer graphene and WSe_2/graphene heterostructures. Under linearly polarized 45--75 G…
Chirality Driven Ratchet Currents in Two-Dimensional Tellurene with an Asymmetric Grating
M. D. Moldavskaya, L. E. Golub, Chang Niu +2
The emergence of the terahertz (THz) ratchet effect is a rapidly expanding field of research that utilizes broken spatial symmetry in low-dimensional materials to rectify alternati…
Bleaching of the Terahertz Magneto-Photogalvanic Effect in CdHgTe Crystals with Kane Fermions
M. D. Moldavskaya, L. E. Golub, V. V. Bel'kov +4
We report the observation and comprehensive study of the complex nonlinear intensity dependence of the magneto-photogalvanic effect (MPGE) current induced by terahertz (THz) radiat…
Magnetophotogalvanic Effects Driven by Terahertz Radiation in CdHgTe Crystals with Kane Fermions
M. D. Moldavskaya, L. E. Golub, V. V. Bel'kov +10
We report on the observation and comprehensive study of the terahertz radiation induced magneto-photogalvanic effect (MPGE) in bulk CdHgTe crystals hosting Kane fermions. The MPGE…
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…
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…
