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…
Tunable valley splitting and bipolar operation in graphene quantum dots
Chuyao Tong, Rebekka Garreis, Angelika Knothe +8
Quantum states in graphene are four-fold degenerate: two fold in spins, and two fold in valleys.Both degrees of freedom can be utilized for qubit preparations. In our bilayer graph…
Coherent Jetting behind a gate-defined Channel in Bilayer Graphene
Carolin Gold, Angelika Knothe, Annika Kurzmann +6
Graphene has evolved as a platform for quantum transport that can compete with the best and cleanest semiconductor systems. Recently, many interesting local properties of carrier t…
Quartet states in two-electron quantum dots in bilayer graphene
Angelika Knothe, Vladimir Fal'ko
Trapping electrons in quantum dots and controlling their collective quantum states is crucial for converting semiconductor structures into bits of quantum information processing. H…
