摘要

这项研究对砷化镓量子点(QD)的掺杂内转变能(IDTE)和归一化掺杂内转变能(NIDTE)进行了深入探讨。量子点含有高斯杂质作为掺杂剂。通过两种不同途径(加法和乘法)施加的高斯白噪声也成为了量子点约束势的一部分。能量值是通过线性变异理论计算得出的。IDTE 和 NIDTE 表现出(取决于是否存在噪声、噪声的进入模式和发生变化的给定物理参数)稳定增长、稳定下降、最大化、最小化和饱和。在整个研究过程中,NIDTE 曲线图有效地突出了 IDTE 曲线图所不具备的一些薄弱特征,并清楚地表明其在实现各种物理参数的影响方面优于 IDTE 曲线图。这项研究的结果有望在阐明含有杂质和受噪声影响的低维纳米结构的光学特性方面发挥重要作用。

Exploration of the normalized intradopant transition energy of GaAs quantum dot under the influence of noise
In this work the intradopant transition energy (IDTE) and the normalized intradopant transition energy (NIDTE) of GaAs quantum dot (QD) have been minutely explored. The QD contains Gaussian impurity as dopant. Gaussian white noise, applied via two different routes (additive and multiplicative), also becomes part of the QD confinement potential. Energy values are calculated using linear variational theory. The IDTE and NIDTE exhibit (depending on presence/absence of noise, mode of entrance of noise and the given physical parameter undergoing change) steady growth, steady fall, maximization, minimization and saturation. Throughout the entire study, the NIDTE plots efficiently highlight some weak features which IDTE plots fail to do and clearly announce their superiority over the IDTE plots in realizing the influences of various physical parameters. The findings of the study are expected to be quite relevant in elucidating the optical properties of low-dimensional nanostructures containing impurity and under the sway of noise.
