Abstract

The puzzling behavior of the transition phase through a quantum dot can be understood in a natural way via a formation of the electron molecule in the quantum dot. In this case the resonance tunneling takes place through the quasi-stationary (doorway) state, which emerges when the number of electrons occupying the dot reaches a certain "critical" value, Ncr. Our estimation of this quantity agrees with the experimental data. The dependence of Ncr on the dot's size is predicted as well.
