2D-Dirac surface states and bulk gap probed via quantum capacitance in a 3D topological insulator
Jimin Wang, Cosimo Gorini, Klaus Richter +3
BiSbTeSe is a 3D topological insulator (3D-TI) with Dirac type surface states and low bulk carrier density, as donors and acceptors compensate each other. Dominating low temper…
Generalized Anderson's theorem for superconductors derived from topological insulators
Lionel Andersen, Aline Ramires, Zhiwei Wang +2
A well-known result in unconventional superconductivity is the fragility of nodal superconductors against nonmagnetic impurities. Despite this common wisdom, BiSe-based top…
Non-local electrical detection of spin-polarized surface currents in the 3D topological insulator BiSbTeSe
Shaham Jafarpisheh, Frank Volmer, Zhiwei Wang +4
The spin-polarized surface states in topological insulators offer unique transport characteristics that make them distinguishable from trivial conductors. Here, we detect the impac…
Evidence for bulk nodal loops and universality of Dirac-node arc surface states in ZrGeXc (Xc = S, Se, Te)
Takechika Nakamura, Seigo Souma, Zhiwei Wang +10
We have performed angle-resolved photoemission spectroscopy (ARPES) on layered ternary compounds ZrGeXc (Xc = S, Se, and Te) with square Ge lattices. ARPES measurements with bulk-s…
Large positive magneto-conductivity at microwave frequencies in the compensated topological insulator BiSbTeSe2
Mahasweta Bagchi, Lea Pitz-Paal, Christoph P. Grams +6
The bulk electronic properties of compensated topological insulators are strongly affected by the self-organized formation of charge puddles at low temperature, but their response…
