Conduction spectroscopy of a proximity induced superconducting topological insulator
Martin P. Stehno, Nico W. Hendrickx, Marieke Snelder +4
The combination of superconductivity and the helical spin-momentum locking at the surface state of a topological insulator (TI) has been predicted to give rise to p-wave supercondu…
Andreev reflection in s-type superconductor proximized 3D topological insulator
E. S. Tikhonov, D. V. Shovkun, V. S. Khrapai +6
We investigate transport and shot noise in lateral N-TI-S contacts, where N is a normal metal, TI is a Bi-based three dimensional topological insulator (3D TI), and S is an s-type…
Observability of surface Andreev bound states in a topological insulator in proximity to an s-wave superconductor
M. Snelder, A. A. Golubov, Y. Asano +1
To guide experimental work on the search for Majorana zero-energy modes, we calculate the superconducting pairing symmetry of a three-dimensional topological insulator in combinati…
Low carrier concentration crystals of the topological insulator BiSbTeSe: a magnetotransport study
Y. Pan, D. Wu, J. R. Angevaare +11
In 3D topological insulators achieving a genuine bulk-insulating state is an important research topic. Recently, the material system (Bi,Sb)(Te,Se) (BSTS) has been prop…
Nonlocal Andreev reflection, fractional charge and current-phase relation in topological bilayer exciton condensate junctions
M. Veldhorst, M. Hoek, M. Snelder +3
We study Andreev reflection and Josephson currents in topological bilayer exciton condensates (TEC). These systems can create 100% spin entangled nonlocal currents with high amplit…
Josephson supercurrent in a topological insulator without a bulk shunt
M. Snelder, C. G. Molenaar, Y. Pan +8
A Josephson supercurrent has been induced into the three-dimensional topological insulator Bi1.5Sb0.5Te1.7Se1.3. We show that the transport in Bi1.5Sb0.5Te1.7Se1.3 exfoliated flake…
