Dispersive sensing of charge states in a bilayer graphene quantum dot
Luca Banszerus, Samuel Möller, Eike Icking +7
We demonstrate dispersive readout of individual charge states in a gate-defined few-electron quantum dot in bilayer graphene. We employ a radio frequency reflectometry circuit, whe…
Minigap and Andreev bound states in ballistic graphene
Luca Banszerus, Florian Libisch, Andrea Ceruti +7
A finite-size normal conductor, proximity-coupled to a superconductor has been predicted to exhibit a so-called minigap, in which quasiparticle excitations are prohibited. Here, we…
Tunable interdot coupling in few-electron bilayer graphene double quantum dots
Luca Banszerus, Alexander Rothstein, Eike Icking +5
We present a highly controllable double quantum dot device based on bilayer graphene. Using a device architecture of interdigitated gate fingers, we can control the interdot tunnel…
Electron-hole crossover in gate-controlled bilayer graphene quantum dots
Luca Banszerus, Alexander Rothstein, Thomas Fabian +10
Electron and hole Bloch states in gapped bilayer graphene exhibit topological orbital magnetic moments with opposite signs near the band edges, which allows for tunable valley-pola…
Exploiting Aharonov-Bohm oscillations to probe Klein tunneling in tunable pn-junctions in graphene
Jan Dauber, Koen J. A. Reijnders, Luca Banszerus +6
One of the unique features of graphene is that the Fermi wavelength of its charge carriers can be tuned electrostatically over a wide range. This allows in principle to tune the tr…
Electrostatic detection of Shubnikov-de-Haas oscillations in bilayer graphene by Coulomb resonances in gate-defined quantum dots
Luca Banszerus, Thomas Fabian, Samuel Möller +11
A gate-defined quantum dot in bilayer graphene is utilized as a sensitive electrometer for probing the charge density of its environment. Under the influence of a perpendicular mag…
