【 摘 要 】

In this work, we investigate the influence of spin-orbit coupling on the magnetic-field dependence of carrier states in a self-assembled quantum dot. The electron and hole energy levels are calculated using the 6-, 8- and 14-band k center dot p models. Through a detailed study within these models, we extract the information about the impact of various spin-orbital coupling channels on the hole P shell. We demonstrate that the most important contribution comes from the influence of shear strain. We show that the complicated magnetic-field dependence of the hole p shell resulting from numerical simulations can be very well fitted using a phenomenological model. We compare the electron and hole g-factors calculated within 8- and 14-band k center dot p models and show that these methods give reasonably good agreement.
