摘要

本文的目的是研究双异质结构双栅InAlAs/InGaAs HEMT中由纳米级对称双三角量子阱(DTQW)组成的通道厚度变化对本征能的影响。本征能通过求解一维时间无关的薛定谔方程在平衡状态下(即没有施加栅极电压时)进行解析计算。沟道厚度的变化表明,不同的屏障宽度和井宽对DTQW系统有独立的影响。特别地,本文研究并给出了不同势垒宽度和阱宽度下的基态和第一激发态。

Effect of variation in channel thickness on eigenenergies of double triangular quantum well in double gate InAlAs/InGaAs HEMT
The aim of this paper is to study the effect on eigenenergies due to variation in channel thickness where the channel comprises of a nanoscale symmetric double triangular quantum well (DTQW) separated by a barrier for double heterostructure double gate InAlAs/InGaAs HEMT. The eigenenergies are calculated analytically by solving one-dimensional (1D) time independent Schrodinger equation in the channel at equilibrium i.e. when no gate voltage is applied. The channel thickness variation implies an independent effect of different barrier width and well widths for the DTQW system. In particular, ground and first excited energy state for various barrier width and well widths are studied and presented in the paper.
