Capacitive energies of quantum dots with hydrogenic impurity

Using the spin density-functional theory, we calculated the electronic structure of quantum dots with a hydrogenic impurity. Changes in the spin-polarization changes and the capacitive energies are investigated as a function of impurity position and the number of electrons. We show that under certain conditions, a spin-blockade condition can be caused by the presence of an impurity.
