superconducting quantum interference through trivial edge states in InAs
Folkert K. de Vries, Tom Timmerman, Viacheslav P. Ostroukh +11
Josephson junctions defined in strong spin orbit semiconductors are highly interesting for the search for topological systems. However, next to topological edge states that emerge…
Quantized conductance and large g-factor anisotropy in InSb quantum point contacts
Fanming Qu, Jasper van Veen, Folkert K. de Vries +10
Due to a strong spin-orbit interaction and a large Landé g-factor, InSb plays an important role in research on Majorana fermions. To further explore novel properties of Majorana fe…
A non-invasive method for nanoscale electrostatic gating of pristine materials
Arjan J. A. Beukman, Fanming Qu, Ken W. West +2
Electrostatic gating is essential for defining and control of semiconducting devices. However, nano-fabrication processes required for depositing gates inevitably degrade the prist…
Decoupling edge versus bulk conductance in the trivial regime of an InAs/GaSb double quantum well using Corbino ring geometry
Binh-Minh Nguyen, Andrey A. Kiselev, Ramsey Noah +13
A Corbino ring geometry is utilized to analyze edge and bulk conductance of InAs/GaSb quantum well structures. We show that edge conductance exists in the trivial regime of this th…
Giant spin-orbit splitting in inverted InAs/GaSb double quantum wells
Fabrizio Nichele, Morten Kjaergaard, Henri J. Suominen +11
Transport measurements in inverted InAs/GaSb quantum wells reveal a giant spin-orbit splitting of the energy bands close to the hybridization gap. The splitting results from the in…
Edge Transport in the Trivial Phase of InAs/GaSb
Fabrizio Nichele, Henri J. Suominen, Morten Kjaergaard +16
We present transport and scanning SQUID measurements on InAs/GaSb double quantum wells, a system predicted to be a two-dimensional topological insulator. Top and back gates allow i…
Electric and Magnetic Tuning Between the Trivial and Topological Phases in InAs/GaSb Double Quantum Wells
Fanming Qu, Arjan J. A. Beukman, Stevan Nadj-Perge +9
Among the theoretically predicted two-dimensional topological insulators, InAs/GaSb double quantum wells (DQWs) have a unique double-layered structure with electron and hole gases…
Edge-mode Superconductivity in a Two Dimensional Topological Insulator
Vlad S. Pribiag, Arjan J. A. Beukman, Fanming Qu +4
Topological superconductivity is an exotic state of matter that supports Majorana zero-modes, which are surface modes in 3D, edge modes in 2D or localized end states in 1D. In the…
