abstract = "We investigate the electronic properties of a sub-micron vertical resonant tunneling structure containing three self-assembled InAs quantum dots (SADs) surrounded by four gate electrodes. The stability diagram is obtained by measuring Coulomb oscillation peaks as a function of the four gate voltages, which are used to modulate the electro-chemical potential of each SAD differently. We assign the charge states in the diagram by identifying three sets of Coulomb oscillation lines. We observe specific anti-crossing behaviors for the two Coulomb oscillation lines in the different sets, reflecting parallel couplings between three SADs in the conduction channel.",
