摘要
The spin relaxation times of the electron have been calculated for phonon assisted transitions between the Zeeman sublevels arising as a result of magnetic impurity doping and applied magnetic field in Mn doped CdTe/ZnTe quantum dots. Taking into account effective mass approximation with four band k.p perturbation theory and incorporating the sp-d exchange interaction, the energies of the split states have been obtained and analyzed with magnetic field and effective concentration. The spin relaxation times have been found to be considerably longer with higher dopant concentration in high magnetic fields at very low temperature.
