Abstract
A theoretical description of far-infrared spectroscopy experiments on self-assembled quantum rings in a magnetic field [Lorke A. et al.: Phys. Rev. Lett. 2000, 84, 2223] is reported which, for the first time, accounts for the full set of experimental resonances. In calculations a 3D effective-mass model with a realistic finite step-like confinement potential, including strain and Coulomb effects is used. A bimodal distribution of ring sizes is assumed.
