Spatially resolved study of backscattering in the quantum spin Hall state
Markus König, Matthias Baenninger, Andrei G. F. Garcia +8
The discovery of the Quantum Spin Hall state, and topological insulators in general, has sparked strong experimental efforts. Transport studies of the Quantum Spin Hall state confi…
Induced superconductivity in the three-dimensional topological insulator HgTe
Luis Maier, Jeroen B. Oostinga, Daniel Knott +7
A strained and undoped HgTe layer is a three-dimensional topological insulator, in which electronic transport occurs dominantly through its surface states. In this Letter, we prese…
Edge state transport through disordered graphene nanoribbons in the quantum Hall regime
Fabian Duerr, Jeroen B. Oostinga, Charles Gould +1
The presence of strong disorder in graphene nanoribbons yields low-mobility diffusive transport at high charge densities, whereas a transport gap occurs at low densities. Here, we…
Terahertz Quantum Hall Effect in a Topological Insulator
A. M. Shuvaev, G. V. Astakhov, G. Tkachov +4
Using THz spectroscopy in external magnetic fields we investigate the low-temperature charge dynamics of strained HgTe, a three dimensional topological insulator. From the Faraday…
