Spin separation of Dirac electrons by twisted and vector optical beams
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
We demonstrate that twisted and vector optical beams can spatially separate two-dimensional electrons with opposite spin projections. Spin accumulation arises from diverging spin c…
Electric and spin-valley currents induced by structured light in 2D Dirac materials
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
Structured optical fields can be used for the injection and control of charge and spin-valley currents. Here, we present a systematical study of these phenomena for interband absor…
Trembling motion of electrons driven by Larmor spin precession
I. Stepanov, M. Ersfeld, A. V. Poshakinskiy +4
We show that the initialization of an ensemble of electrons in the same spin state in strained n-InGaAs subject to a perpendicular magnetic field triggers an AC electric current at…
Second harmonic generation due to spatial structure of radiation beam
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
We show that spatially structured radiation generates second harmonic in a two-dimensional system even if the system is homogeneous and isotropic. The effect originates from non-lo…
Terahertz Magnetospectroscopy of Cyclotron Resonances from Topological Surface States in Thick Films of CdHgTe
M. Otteneder, D. Sacré, I. Yahniuk +10
We present studies of the cyclotron resonance (CR) in thick CdHgTe films with different cadmium concentrations corresponding to inverted and normal band order, as well…
Valley polarization induced second harmonic generation in graphene
L. E. Golub, S. A. Tarasenko
The valley degeneracy of electron states in graphene stimulates intensive research of valley-related optical and transport phenomena. While many proposals on how to manipulate vall…
