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…
