| Resumo | |
Combining atomistic methods and effective mass approaches, the magnetic field response of Mn-doped deformed quantum dots has been characterized. The defect-induced asymmetry triggers unavoidable spin-orbit coupling effects that become more relevant the smaller the quantum confinement. Thus, the expected spin splitting modulation by the exchange interaction between the confined carriers and the Mn impurity is tuned by the intertwining of spatial geometry and magnetic field. Furthermore, ab initio calculations are presented for assessing the exchange interaction term and its response to confinement effects at the atomistic level. (AU) | |
