Abstract
We show that the resonance energies associated with tunneling through a typical semiconductor dot depend strongly on quantum-mechanical many-body effects in the dot. These resonance energies IcannotP be written as the sum of single-particle confinement energies and constant Coulomb charging energies, and the magnetic-field dependence of these resonance energies differs greatly from the single-electron result. The semiclassical description of Coulomb charging effects in terms of capacitances is shown to be incorrect.
