Proximity-induced superconductivity in a bilayer graphene quantum point contact
Clara Galante-Agero, Christoph Adam, Artem O. Denisov +9
We report the realization of a gate-defined quantum point contact (QPC) in bilayer graphene proximitized by a single aluminum superconducting electrode. Superconducting correlation…
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…
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…
Microwave spectroscopy of few-carrier states in bilayer graphene quantum dots
Max J. Ruckriegel, Christoph Adam, Rebecca Bolt +8
Bilayer graphene is a maturing material platform for gate-defined quantum dots that hosts long-lived spin and valley states. Implementing solid-state qubits in bilayer graphene req…
Spin-valley 0.7 anomaly in bilayer graphene/WSe quantum point contacts
Jonas D. Gerber, Efe Ersoy, Michele Masseroni +10
We report a well-resolved 0.7 conductance anomaly at in bilayer graphene/WSe quantum point contacts. Proximity-enhanced spin-orbit coupling splits the f…
