Excitations in doped quantum dot driven by linear and non-linear drift of impurity

We explore the excitation profile of a repulsive impurity doped quantum dot induced by linear and non-linear drift of the dopant location. We have considered Gaussian impurity centers. The investigation reveals the roles subtly played by the region of influence of the dopant in conjunction with the mode of dopant propagation to modulate the excitation pattern. The investigation also reveals a change in the relative dominance of various factors in influencing the excitation rate associated with a change in the mode of dopant shift.
