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…
Optical probing of correlation driven liquid-to-insulator transition in 2D electron gas
F. Dionigi, F. Rossella, V. Bellani +5
We study the quantum Hall liquid and the metal-insulator transition in a high mobility two dimensional electron gas, by means of photoluminescence and magneto-transport. In the int…
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…
