It is known experimentally that stable charged-exciton complexes can exist in low-dimensional semiconductor nanostructures. Much less is known about the properties of such charged-exciton complexes since three-body problems are very difficult to solve, even numerically. Here we introduce the correla

The influence of local charge separation in self-organized In(Ga)As/GaAs quantum dots (QDs) on the exciton dynamics under resonant excitation of the confined exciton in the first excited state is investigated by time-resolved photoluminescence spectroscopy. The oscillator strength and the relaxation

We have investigated exciton -phonon coupling and a zero-phonon exciton absorption line shape for lens-shaped quantum dots (QDs). Such dots occur in quasi-monolayer semiconductor heterostructures due to the interfacial roughness making quasi-2D excitons localize in lens-shaped quantum dot-like islan

## Abstract The binding energy of the ground state of a charged exciton‐donor complex in a spherical semiconductor quantum dot in the presence of a homogeneous magnetic field has been calculated. The theoretical analysis is carried out using a variational approach in the framework of the adiabatic
