Influence of external field and consequent impurity breathing on excitation profile of doped quantum dots

► The excitation profile of impurity doped quantum dot has been investigated. ► The dot is subject to external oscillatory field. ► Concomitant time-dependence in spatial stretch of impurity has been introduced. ► Minimization in excitation rate is observed as a function of two oscillation ratios. ► Role of dopant location has also been analyzed.
