Abstract

We present results of measurements of the I-V characteristics of a unique parallel double dot where the current flows vertically but the coupling is lateral. Probed by asymmetry of Coulomb diamonds in the standard double-dot honeycomb stability diagram, we are able to discern in what sequence electrons are added in the two dots.
