Superballistic electron flow through a point contact in a Ga[Al]As heterostructure
Lev V. Ginzburg, Carolin Gold, Marc P. Röösli +5
We measure electronic transport through point contacts in the high-mobility electron gas in a Ga[Al]As heterostructure at different temperatures and bulk electron densities. The co…

Auger-spectroscopy in quantum Hall edge channels: a possible resolution to the missing energy problem
T. Krähenmann, S. G. Fischer, M. Röösli +6
Quantum Hall edge channels offer an efficient and controllable platform to study quantum transport in one dimension. Such channels are a prospective tool for the efficient transfer…

Stable Branched Electron Flow
B A Braem, C Gold, S Hennel +6
The pattern of branched electron flow revealed by scanning gate microscopy shows the distribution of ballistic electron trajectories. The details of the pattern are determined by t…
