Abstract
We studied the exciton energy in a type II quantum disk as a function of the magnetic field, disk radius R and height d. We found angular momentum transitions for dots with d >> 2R. Application of an electric field perpendicular to the disk showed a non-linear Stark shift. In the case of three vertically coupled dots angular momentum transistions were found for small interdot distances which disappeared with increasing interdot distance.
