Two-step breakdown of a local v = 1 quantum Hall state
Masayuki Hashisaka, Koji Muraki, Toshimasa Fujisawa
We report quantum Hall effect breakdown of a local filling factor v_local = 1 state formed in a bulk v_bulk = 2 system in an AlGaAs/GaAs heterostructure. When a finite source-drain…
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…
Spectroscopic study on hot-electron transport in a quantum Hall edge channel
Tomoaki Ota, Shunya Akiyama, Masayuki Hashisaka +2
Hot electron transport in a quantum Hall edge channel of an AlGaAs/GaAs heterostructure is studied by investigating the energy distribution function in the channel. Ballistic hot-e…
