Edge channel confinement in a bilayer graphene -- quantum dot
Hiske Overweg, Peter Rickhaus, Marius Eich +6
We combine electrostatic and magnetic confinement to define a quantum dot in bilayer graphene. The employed geometry couples -doped reservoirs to a -doped dot. At magnetic fi…
Giant valley-isospin conductance oscillations in ballistic graphene
Clevin Handschin, Péter Makk, Peter Rickhaus +6
At high magnetic fields the conductance of graphene is governed by the half-integer quantum Hall effect. By local electrostatic gating a \textit{p-n} junction perpendicular to the…
Electrostatically induced quantum point contact in bilayer graphene
Hiske Overweg, Hannah Eggimann, Xi Chen +10
We report the fabrication of electrostatically defined nanostructures in encapsulated bilayer graphene, with leakage resistances below depletion gates as high as G.…
Microwave Photodetection in an Ultraclean Suspended Bilayer Graphene pn Junction
Minkyung Jung, Peter Rickhaus, Simon Zihlmann +2
We explore the potential of bilayer graphene as a cryogenic microwave photodetector by studying the microwave absorption in fully suspended clean bilayer graphene pn junctions in t…
Fabry-Pérot resonances in a graphene/hBN Moiré superlattice
Clevin Handschin, Péter Makk, Peter Rickhaus +5
While Fabry-Pérot resonances and Moiré superlattices are intensively studied in graphene on hexagonal boron nitride (hBN), the two effects have not been discussed in their coexiste…
