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 of a double quantum dot
David Kealhofer, Christoph Adam, Max J. Ruckriegel +7
We use charge sensing to detect entropy changes in a double quantum dot defined by electrostatic gating of a GaAs/AlGaAs heterostructure. This system can be tuned to be two separat…
Tunable spin-orbit splitting in bilayer graphene/WSe quantum devices
Jonas D. Gerber, Efe Ersoy, Michele Masseroni +14
Bilayer graphene (BLG)-based quantum devices represent a promising platform for emerging technologies, such as quantum computing and spintronics. However, their intrinsically weak…
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…
