Excitations in doped quantum dot driven by periodically fluctuating impurity domain

Abstract

We explore the excitation profile of a repulsive impurity doped quantum dot induced by a periodically fluctuating impurity domain. We have considered Gaussian impurity centers. The investigation reveals the effects of the dopant coordinate and dopant strength in conjunction with the oscillating impurity domain to modulate the excitation pattern. The investigation also reveals the maximization in the excitation rate for some typical range of values of dopant location and dopant strength.

Excitations in doped quantum dot induced by accelerating impurity center

“…Recently, we have made some investigations on the excitation profiles of the doped quantum dots owing to time-dependent modulation of impurity potential. [25][26][27][28] In this paper we have attempted to investigate the excitations in the doped quantum dot that is induced by a time-dependent propagation of the dopant coordinate. The dopant, during its motion, experiences several jolts that change its velocity randomly.…”
