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…
Giant anomalous Josephson effect as a probe of spin texture in topological insulators
Niklas Hüttner, Andreas Costa, Leandro Tosi +9
Surface states of topological insulators feature chiral spin-momentum locking. When such states are used as weak link between two superconductors, their spin texture gives rise to…
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…
