Local signatures of electron-electron scattering in an electronic cavity
Carolin Gold, Beat A. Bräm, Richard Steinacher +7
We image equilibrium and non-equilibrium transport through a two-dimensional electronic cavity using scanning gate microscopy (SGM). Injecting electrons into the cavity through a q…
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…
Imaging signatures of the local density of states in an electronic cavity
Carolin Gold, Beat A. Bräm, Michael S. Ferguson +9
We use Scanning Gate Microscopy to study electron transport through an open, gate-defined resonator in a Ga(Al)As heterostructure. Raster-scanning the voltage-biased metallic tip a…
Shell Filling and Trigonal Warping in Graphene Quantum Dots
Rebekka Garreis, Angelika Knothe, Chuyao Tong +8
Transport measurements through a few-electron circular quantum dot in bilayer graphene display bunching of the conductance resonances in groups of four, eight and twelve. This is i…
Scanning Gate Microscopy of Localized States in a gate-defined Bilayer Graphene Channel
Carolin Gold, Annika Kurzmann, Kenji Watanabe +3
We use Scanning Gate Microscopy to demonstrate the presence of localized states arising from potential inhomogeneities in a 50nm-wide, gate-defined conducting channel in encapsulat…
Gap Opening in Twisted Double Bilayer Graphene by Crystal fields
Peter Rickhaus, Giulia Zheng, Jose L. Lado +12
Crystal fields occur due to a potential difference between chemically different atomic species. In Van-der-Waals heterostructures such fields are naturally present perpendicular to…
