Differential conductance in a Quantum Dot


Differential conductance G versus source-drain voltage VSD and plunger gate voltage VG. The blue (red) areas correspond to low (high) G. Coulomb blockaded regions are indicated by N-1, N, etc.
A light source illuminates the figure from the bottom to make the contours of peaks more clearly visible.
