Competition between the Superconducting Proximity Effect and Coulomb Interactions in a Graphene Andreev Interferometer
Fabio Deon, Sandra Šopić, Alberto F. Morpurgo
We have investigated transport through graphene Andreev interferometers exhibiting reentrance of the superconducting proximity effect. We observed a crossover in the Andreev conduc…
Proximity effect in a two dimensional electron gas probed with a lateral quantum dot
Fabio Deon, Vittorio Pellegrini, Francesco Giazotto +3
We report low-temperature transport measurements performed on a planar Nb-InGaAs-Nb proximity Josephson junction hosting a gate-defined lateral quantum dot in the weak-link. We fir…
Quantum dot spectroscopy of proximity-induced superconductivity in a two-dimensional electron gas
Fabio Deon, Vittorio Pellegrini, Francesco Giazotto +3
We report the realization of a hybrid superconductor-quantum dot device by means of top-down nanofabrication starting from a two dimensional electron gas in a InGaAs/InAlAs semicon…
Probing the local temperature of a 2DEG microdomain with a quantum dot: measurement of electron-phonon interaction
Simone Gasparinetti, Fabio Deon, Giorgio Biasiol +3
We demonstrate local detection of the electron temperature in a two-dimensionalmicrodomain using a quantum dot. Our method relies on the observation that a temperature bias across…
Singlet-triplet transition in a few-electron lateral InGaAs-InAlAs quantum dot
F. Deon, V. Pellegrini, F. Carillo +4
The magnetic-field evolution of Coulomb blockade peaks in lateral InGaAs/InAlAs quantum dots in the few-electron regime is reported. Quantum dots are defined by gates evaporated on…
