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…
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…
Composite super-moiré lattices in double aligned graphene heterostructures
Zihao Wang, Yi Bo Wang, J. Yin +23
When two-dimensional atomic crystals are brought into close proximity to form a van der Waals heterostructure, neighbouring crystals can start influencing each others electronic pr…
Tunable Valley Splitting due to Topological Orbital Magnetic Moment in Bilayer Graphene Quantum Point Contacts
Yongjin Lee, Angelika Knothe, Hiske Overweg +10
In multivalley semiconductors, the valley degree of freedom can be potentially used to store, manipulate and read quantum information, but its control remains challenging. The vall…
Minibands in twisted bilayer graphene probed by magnetic focusing
A. I. Berdyugin, B. Tsim, P. Kumaravadivel +9
Magnetic fields force ballistic electrons injected from a narrow contact to move along skipping orbits and form caustics. This leads to pronounced resistance peaks at nearby voltag…
Semimetallic features in quantum transport through a gate-defined point contact in bilayer graphene
Thomas L M Lane, Angelika Knothe, Vladimir I Fal'ko
We demonstrate that, at the onset of conduction, an electrostatically defined quantum wire in bilayer graphene (BLG) with an interlayer asymmetry gap may act as a 1D semimetal, due…
