Abstract

The electronic states of a parabolic quantum dot in a magnetic field are studied with the spin-orbit interaction included. The analytical formulae for the ground-state energy of the interacting system are derived. The spin-orbit interaction introduces a new feature into the far infra-red absorption spectrum, namely a splitting of the two principal modes. This conclusion is compared with the charging experiments of Ashoori et al. and the far infra-red absorption measurements of Demel et al.

A model of an exciton confined in a quantum dot is also analyzed. At a critical dot-size, an additional strong line in the photo-luminescence spectrum appears, a consequence of the occurrence of a meta-stable weakly excited state.
