摘要

本工作的目的是计算包含不同尺寸量子点的量子点二维周期超晶格中的电子迁移率。用紧束缚法计算了周期晶格的能级和本征态,并进行了仿真。引入不同尺寸的非周期量子点作为扰动势散射中心,并将其效应包含在费米分布中,从而得到一个温度相关的迁移率张量,便于与实验数据进行比较。

Efficient Mobility Calculation for Quantum Dot Superlattices
The aim of this work is to calculate the electron mobility in a two dimensional periodic superlattice of quantum dots containing different-sized quantum dots. A simulation has been carried out using the tight binding method for calculating the energy levels and eigenstates of the periodic lattice. The different sized, non-periodic quantum dots are introduced as perturbed potential scattering centers and their effect has been included in the Fermi distribution to obtain a temperature dependent mobility tensor for easy comparison with experimental data.
