Abstract
In this study, we have investigated the effect of the impurity dependent dielectric screening function on the diamagnetic susceptibility and the binding energy of a shallow-donor impurity confined in a GaAs conical quantum dot (CQD). The calculations have been made within the effective mass approximation, variational method and considering an infinite confining potential. Our results suggest that the effects of the variation of geometrical parameters of CQD are playing a pronounce influence on the diamagnetic susceptibility and the binding energy. The results show that the diamagnetic susceptibility depends strongly on the impurity position and it severely affected by the geometrical parameters of CQD.
