Charging and infrared spectroscopy of self-assembled quantum dots in a magnetic field

Abstract
The few-electron states of the lens-shaped self-assembled quantum dots in the magnetic field are studied. The calculated charging and infrared absorption spectra reflect the magnetic-field-induced transitions between different states of interacting electrons. The theoretical results compare well with recent experiments by Drexler et al. [Phys. Rev. Lett. 73, 2252 (1994)]. New features are predicted to occur at higher magnetic fields. © 1996 The American Physical Society.
