Monolithic hybrid quantum dot devices in superconducting twisted bilayer graphene
Alexandra Mestre-TorÃ, Marta Perego, Clara Galante Agero +5
Gate-tunable superconductivity in magic-angle twisted bilayer graphene (MATBG) has enabled the realization of superconducting devices, such as Josephson junctions, within a single…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Non-equilibrium transport reveals energy level degeneracy
Artem O. Denisov, Christoph Adam, Hadrien Duprez +7
We demonstrate a method to determine energy level degeneracies using non-equilibrium electronic transport through voltage-biased quantum dots. We establish the general validity of…
Entropy spectroscopy of a bilayer graphene quantum dot
Christoph Adam, Hadrien Duprez, Natalie Lehmann +13
We measure the entropy change of charge transitions in an electrostatically defined quantum dot in bilayer graphene. Entropy provides insights into the equilibrium thermodynamic pr…
Pearl-Vortex Tunneling in Magic-Angle Twisted Graphene
Marta Perego, Peter Koopmann, Clara Galante Agero +8
Twisted graphene provides a tunable platform for studying superconductivity in two dimensions. In the presence of electric currents and magnetic fields, vortices determine the phen…
Time-resolved Charge Detection in Transition Metal Dichalcogenide Quantum Dots
Markus Niese, Michele Masseroni, Clara Scherm +10
We investigate electronic transport through gate-defined quantum dots in molybdenum disulfide MoS using an integrated charge detector. We observe a crossover from two weakly co…
