Proximity gap probed by cotunneling spectroscopy. The color bar is the differential conductance G (e2/h) as a function of backgate voltage VBG and source-drain voltage bias VSD for a high, b middle, and c low backgate voltages VBG. Blue lines are averaged over 20 cross-sections taken in the center of the Coulomb blockade diamonds. The cross-sections shown in c are averaged over the Coulomb blockade region between the Coulomb resonances
