Multi-probe analysis to separate edge currents from bulk currents in quantum spin Hall insulators and to analyze their temperature dependence
S. Benlenqwanssa, S. S. Krishtopenko, M. Meyer +13
We present a multi-probe transport analysis that effectively separates bulk and edge currents in large Hall bar devices with standard geometries. Applied to transport measurements…
Quantum Hall effect and zero plateau in bulk HgTe
M. L. Savchenko, D. A. Kozlov, S. S. Krishtopenko +4
The quantum Hall effect, which exhibits a number of unusual properties, is studied in a gated 1000-nm-thick HgTe film, nominally a three-dimensional system. A weak zero plateau of…
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…
Roles of band gap and Kane electronic dispersion in the THz-frequency nonlinear optical response in HgCdTe
Davide Soranzio, Elsa Abreu, Sarah Houver +7
Materials with linear electronic dispersion often feature high carrier mobilities and unusually strong nonlinear optical interactions. In this work, we investigate the THz nonlinea…
Coexistence of Topological and Normal Insulating Phases in Electro-Optically Tuned InAs/GaSb Bilayer Quantum Wells
Manuel Meyer, Tobias Fähndrich, Sebastian Schmid +7
We report on the coexistence of both normal and topological insulating phases in InAs/GaSb bilayer quantum well induced by the built-in electric field tuned optically and electrica…
