Probing charge noise in bilayer graphene quantum dots by Landau-Zener-Stückelberg-Majorana spectroscopy
Katrin Hecker, Samuel Möller, Tobias Deußen +6
Charge noise is an important factor limiting qubit coherence and relaxation in solid-state devices. In bilayer graphene (BLG) quantum dots, recently established as a promising plat…
Transport gap in side-gated graphene constrictions
F. Molitor, A. Jacobsen, C. Stampfer +3
We present measurements on side gated graphene constrictions of different geometries. We characterize the transport gap by its width in back gate voltage and compare this to an ana…
Graphene quantum dots: Beyond a Dirac billiard
F. Libisch, C. Stampfer, J. Burgdörfer
We present realistic simulations of quantum confinement effects in ballistic graphene quantum dots with linear dimensions of 10 to 40 nm. We determine wavefunctions and energy leve…
Coulomb oscillations in three-layer graphene nanostructures
J. Guettinger, C. Stampfer, F. Molitor +3
We present transport measurements on a tunable three-layer graphene single electron transistor (SET). The device consists of an etched three-layer graphene flake with two narrow co…
