Positive Terahertz Photoconductivity in CdHgTe Under Hydrostatic Pressure
Ivan Yahniuk, Dmitriy A. Kozlov, Mariya D. Moldavskaya +10
Positive terahertz photoconductivity is observed at room temperature in CdHgTe thin films with different Cd contents. We show that electron gas heating caused by Drude-like absorpt…
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…
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…
Edge photocurrent in bilayer graphene due to inter-Landau-level transitions
S. Candussio, M. V. Durnev, S. Slizovskiy +9
We report the observation of the resonant excitation of edge photocurrents in bilayer graphene subjected to terahertz radiation and a magnetic field. The resonantly excited edge ph…
