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…
Quantum confinement of the Dirac surface states in topological-insulator nanowires
Felix Münning, Oliver Breunig, Henry F. Legg +5
The non-trivial topology of the three-dimensional (3D) topological insulator (TI) dictates the appearance of gapless Dirac surface states. Intriguingly, when a 3D TI is made into a…
Novel self-epitaxy for inducing superconductivity in the topological insulator (Bi1-xSbx)2Te3
Mengmeng Bai, Fan Yang, Martina Luysberg +6
Using the superconducting proximity effect for engineering a topological superconducting state in a topological insulator (TI) is a promising route to realize Majorana fermions. Ho…
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…
Nano-mosaic of Topological Dirac States on the Surface of Pb5Bi24Se41 Observed by Nano-ARPES
Kosuke Nakayama, Seigo Souma, Chi Xuan Trang +9
We have performed scanning angle-resolved photoemission spectroscopy with a nanometer-sized beam spot (nano-ARPES) on the cleaved surface of Pb5Bi24Se41, which is a member of the (…
