Herein, the influence of Gaussian white noise on static quadrupole polarizability (SQP) of the impurity‐doped quantum dots (QDs) is studied. The SQP profiles are critically analyzed as several physical quantities are varied over a range in the absence and presence of noise. The introduction of noise to the system is accomplished via two different routes viz. “additive” and “multiplicative.” SQP profiles consist of noticeable features like maximization, minimization, and saturation in the absence of noise and presence of additive noise. However, on most occasions, the SQP profile becomes devoid of any noticeable characteristics in the presence of multiplicative noise. The multiplicative noise plays some noticeable role only during the direct variation in confinement energy. Herein, the exclusive role of additive noise having strength around a typical value for the generation of large SQP is highlighted. The findings bear mentionable importance on the nonlinear optical properties of QD‐based devices under the aegis of noise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
