Counterflowing edge current and its equilibration in quantum Hall devices with sharp edge potential: Roles of incompressible strips and contact configuration
T. Akiho, H. Irie, K. Onomitsu +1
We report the observation of counterflowing edge current in InAs quantum wells which leads to the breakdown of quantum Hall (QH) effects at high magnetic fields. Counterflowing edg…

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…
