Abstract
The electronic structure of lens-shaped InGaAs self-assembled quantum dots (SADs) is studied as a function of the dot size, the confining potential and the magnetic field. Numerical calculations show the formation of the electronic shell structure to be well approximated by a Fock - Darwin energy spectrum. Many-body effects in electronic and optical properties of SADs charged with electrons and/or excitons are investigated using exact diagonalization techniques. The capacitance, infrared and interband absorption/emission spectra are calculated as a function of the number of particles, the size and the magnetic field.
