高温下InAs/GaSb型II超晶格中电子迁移率的研究

Study of the Electron Mobility in InAs/GaSb Type II Superlattices at High Temperatures

Sara Safa, Asghar Asgari

摘要:

本文研究了温度对InAs/GaSb Ⅱ型超晶格中电子迁移率的影响,采用数值有限差分法求解K.P哈密顿量,计算了Ⅱ型超晶格的能带结构和波函数。模型中考虑了合金散射、声学声子散射和光学声子散射等主要散射机制。得到的电子迁移率的第二类SL的结构参数和不同的散射参数依赖。我们的计算结果与已发表的实验数据的比较表明是在良好的协议。

英文摘要:

In this paper, we present a study of the effects of temperature on the electron mobility in InAs/GaSb type-II superlattices (SLs) in which the band structures and wave functions are calculated by solving the K.P Hamiltonian using the numerical Finite Difference method. In the model the dominant scattering mechanisms such as alloy scattering, acoustic phonon scattering and optical phonon scattering are taken into account. The obtained electron mobility of the type II SLs is depended on the structural parameters and different scattering parameters. A comparison of our calculated results with published experimental data is shown to be in good agreement.
