Energy gap tuning and gate-controlled topological phase transition in InAs/InGaSb composite quantum wells
H. Irie, T. Akiho, F. Couëdo +3
We report transport measurements of strained InAs/InGaSb composite quantum wells (CQWs) in the quantum spin Hall phase, focusing on the control of the energy gap thro…

Pseudospin Berry phase as a signature of nontrivial band topology in a two-dimensional system
F. Couëdo, H. Irie, T. Akiho +3
Electron motion in crystals is governed by the coupling between crystal momentum and internal degrees of freedom such as spin implicit in the band structure. The description of thi…

Single-edge transport in an InAs/GaSb quantum spin Hall insulator
François Couëdo, Hiroshi Irie, Kyoichi Suzuki +2
We report transport measurements in a single edge channel of an InAs/GaSb quantum spin Hall insulator, where the conduction occurs through only one pair of counterpropagating edge…
