Andreev reflection at the edge of a two-dimentional semimetal
A. Kononov, S. V. Egorov, Z. D. Kvon +3
We investigate electron transport through the interface between a niobium superconductor and the edge of a two-dimensional semimetal, realized in a 20~nm wide HgTe quantum well. Ex…
Probing quantum capacitance in a 3D topological insulator
D. A. Kozlov, D. Bauer, J. Ziegler +6
We measure the quantum capacitance and probe thus directly the electronic density of states of the high mobility, Dirac type of two-dimensional electron system, which forms on the…
Magnetotransport in Double Quantum Well with Inverted Energy Spectrum: HgTe/CdHgTe
M. V. Yakunin, A. V. Suslov, M. R. Popov +3
We present the first experimental study of the double-quantum-well (DQW) system made of 2D layers with inverted energy band spectrum: HgTe. The magnetotransport reveals a considera…
Evidence on the macroscopic length scale spin coherence for the edge currents in a narrow HgTe quantum well
A. Kononov, S. V. Egorov, Z. D. Kvon +3
We experimentally investigate spin-polarized electron transport between two ferromagnetic contacts, placed at the edge of a two-dimensional electron system with band inversion. The…
Cyclotron Resonance Assisted Photocurrents in Surface States of a 3D Topological Insulator Based on a Strained High Mobility HgTe Film
K. -M. Dantscher, D. A. Kozlov, P. Olbrich +12
We report on the observation of cyclotron resonance induced photocurrents, excited by continuous wave terahertz radiation, in a 3D topological insulator (TI) based on an 80 nm stra…
Shot noise of the edge transport in the inverted band HgTe quantum wells
E. S. Tikhonov, D. V. Shovkun, Z. D. Kvon +3
We investigate the current noise in HgTe-based quantum wells with an inverted band structure in the regime of disordered edge transport. Consistent with previous experiments, the e…
