Abstract
AbstractThe study meticulously inspects thetime‐average excitation rate (TAER)of lowest energy state electronic probability ofGaAs quantum dot (QD)to the higher energy states. The excitation occurs as theanharmonic potential(a part of QD confinement) starts varying with time eitherperiodicallyorrandomly. The anharmonic potential is characterized by eitherevenoroddparity.Gaussian white noise (GWN)has also been introduced to the QD either viaadditiveormultiplicativemode. The study announces that the coupled impact of the given physical quantity, the symmetry of the anharmonicity, presence/absence of noise, the route of entrance of noise, and the nature of time progress of anharmonicity constant, ultimately regulates and fine‐tunes the attributes of the TAER diagrams. The TAER diagrams comprise of regular rise, regular fall, maximization (pertinent to production of high value ofnonlinear optical (NLO) properties), minimization and saturation (pertinent todynamic freezing). The outcomes of the study seem to be recognizable in various applications of devices containing QD.
