THE INTERPLAY BETWEEN MAGNETIC-FIELD AND ELECTRON-ELECTRON INTERACTION ON TRANSPORT THROUGH QUANTUM DOTS

We study the combined effects of electron-electron interaction and per pendicular magnetic fields on transport through a weakly-coupled semic onductor quantum dot in several regimes of interest. An extensive anal ysis of the magnitudes relevant for transport, such as addition spectr a and single-electron tunneling rates, is carried out. We find that, i n addition to the Coulomb energy gap in tunneling, responsible for the Coulomb blockade effects, the electron-electron interaction strongly affects the single-particle tunneling rates.
