Ballistic hot-electron transport in a quantum Hall edge channel defined by a double gate
Shunya Akiyama, Taichi Hirasawa, Yuya Sato +3
Ballistic transport of hot electrons in a quantum Hall edge channel is attractive for studying electronic analog of quantum optics, where the edge potential profile is an important…
Charge equilibration in integer and fractional quantum Hall edge channels in a generalized Hall-bar device
Chaojing Lin, Ryota Eguchi, Masayuki Hashisaka +3
Charge equilibration between quantum-Hall edge states can be studied to reveal geometric structure of edge channels not only in the integer quantum Hall (IQH) regime but also in th…
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…
