Abstract

Semiconductor quantum dots characterized by a strong dielectric mismatch with their environment arestudied theoretically through direct diagonalization of the many-body Hamiltonian. The enhancement of theelectron-electron Coulomb interaction, arising from polarization effects, is found to induce a strong increase inaddition energies with increasing dielectric mismatch. For large dielectric mismatch, the excited many-bodystates can undergo reconstructions as the dot is filled with carriers even in the absence of external magneticfields.
