Abstract

We have measured the tunnelling current through a two-dimensional quantum dot formed at the intersection between two wires. Near the onset, the current-voltage curves display a step-like current structure characteristic of incremental charging of the quantum well controlled by Coulomb blockade. Using a magnetic field, we probe the energy levels within the dot when charged with either one or two electrons. These results are compared to the Darwin-Fock calculation for a parabolic quantum dot.
