Coexisting topological hinges and 1D Rashba states in BiSb revealed by the Josephson effect
Biplab Bhattacharyya, Stijn R. de Wit, Zhen Wu +4
Second-order topological insulating (SOTI) states in three-dimensional materials are helical one-dimensional hinge states. Inducing superconductivity in these states leads to gaple…
Gold-induced nanowires on the Ge(100) surface yield a 2D, and not a 1D electronic structure
Nick de Jong, René Heimbuch, Sebas Eliens +5
Atomic nanowires on semiconductor surfaces induced by the adsorption of metallic atoms have attracted a lot of attention as possible hosts of the elusive, Tomonaga-Luttinger liquid…
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…
Angle-resolved and core-level photoemission study of interfacing the topological insulator Bi1.5Sb0.5Te1.7Se1.3 with Ag, Nb and Fe
N. de Jong, E. Frantzeskakis, B. Zwartsenberg +7
Interfaces between a bulk-insulating topological insulator (TI) and metallic adatoms have been studied using high-resolution, angle-resolved and core-level photoemission. Fe, Nb an…
Micro-metric electronic patterning of a topological band structure using a photon beam
Emmanouil Frantzeskakis, Nick de Jong, Berend Zwartsenberg +12
In an ideal 3D topological insulator (TI), the bulk is insulating and the surface conducting due to the existence of metallic states that are localized on the surface; these are th…
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…
Superconductivity in the doped topological insulator CuBiSe under high pressure
T. V. Bay, T. Naka, Y. K. Huang +3
We report a high-pressure single crystal study of the topological superconductor CuBiSe. Resistivity measurements under pressure show superconductivity is depressed smo…
