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

Additive Gaussian white noise modulated excitation kinetics of impurity doped quantum dots: Role of confinement sources

“…The time-independent Schrödinger equation has been solved using variational method expressing the trial wave function ψ(x, y) as a superposition of the product of harmonic oscillator eigenfunctions [41,42]. In the linear variational calculation, an appreciably large number of basis functions have been exploited after making the required convergence test.…”

“…can be calculated where T is the total time of dynamic evolution [41,42]. It needs to be realized that the role of ω 0 on excitation is no longer straightforward, rather it is quite subtle.…”

“…The phenomenon also plays some important role in the population transfer among the exciton states in QD [37,40]. Of late, we have performed some inspections which deal with excitation in doped QD's that has been triggered by some external time-varying field [41,42].…”

“…Recently, it has also been shown that some typical orientation of magnetic field can tune the binding energy of surface impurities in QD's [53]. Moreover, nowadays the importance of dopant location in fabricating dot properties are well recognized [2,8,20,24,26,41,42]. The distance dependency of dopant unfolds promising opportunities to engineer QD electron dynamics in doped heterostructures.…”
