Edge photocurrent driven by THz electric field in bi-layer graphene
S. Candussio, M. V. Durnev, S. A. Tarasenko +10
We report on the observation of edge electric currents excited in bi-layer graphene by terahertz laser radiation. We show that the current generation belongs to the class of second…
Edge currents driven by terahertz radiation in graphene in quantum Hall regime
H. Plank, M. V. Durnev, S. Candussio +9
We observe that the illumination of unbiased graphene in the quantum Hall regime with polarized terahertz laser radiation results in a direct edge current. This photocurrent is cau…
Terahertz Photogalvanic Spectroscopy of Three Dimensional Topological Insulators
Helene Plank, Sergey D. Ganichev
The paper overviews experimental and theoretical studies of photogalvanic effects induced in BiSbTe- based three dimensional topological insulators by polarized terahertz radiation…
Infrared/Terahertz Spectra of the Photogalvanic Effect in (Bi,Sb)Te based Three Dimensional Topological Insulators
H. Plank, J. Pernul, S. Gebert +9
We report on the systematic study of infrared/terahertz spectra of photocurrents in (Bi,Sb)Te based three dimensional topological insulators. We demonstrate that in a wide range of…
Circular and Linear Photogalvanic Effects in Type-II GaSb/InAs Quantum Well Structures in the Inverted Regime
H. Plank, S. A. Tarasenko, T. Hummel +5
We report on the observation of photogalvanic effects induced by terahertz radiation in type-II GaSb/InAs quantum wells with inverted band order. Photocurrents are excited at obliq…
Opto-Electronic Characterization of Three Dimensional Topological Insulators
Helene Plank, Sergey N. Danilov, Vasily V. Bel'kov +6
We demonstrate that the terahertz/infrared radiation induced photogalvanic effect, which is sensitive to the surface symmetry and scattering details, can be applied to study the hi…
Photon Drag Effect in (BiSb)Te Three Dimensional Topological Insulators
H. Plank, L. E. Golub, S. Bauer +10
We report on the observation of a terahertz radiation induced photon drag effect in epitaxially grown - and -type (BiSb)Te three dimensional topolog…
Magnetooptical Study of Zeeman Effect in Mn modulation-doped InAs/InGaAs/InAlAs Quantum Well Structures
Ya. V. Terent'ev, S. N. Danilov, H. Plank +10
We report on a magneto-photoluminescence (PL) study of Mn modulation-doped InAs/InGaAs/InAlAs quantum wells. Two PL lines corresponding to the radiative recombination of photoelect…
Room temperature high frequency transport of Dirac fermions in epitaxially grown Sb_2Te_3 based topological insulators
P. Olbrich, L. E. Golub, T. Herrmann +11
We report on the observation of photogalvanic effects in epitaxially grown Sb_2Te_3 three-dimensional (3D) topological insulators (TI). We show that asymmetric scattering of Dirac…
