Electron Bloch Oscillations and Electromagnetic Transparency of Semiconductor Superlattices in Multi-Frequency Electric Fields
摘要：
研究了在多频周期和非周期电场作用下，半导体超晶格（具有不同的微带色散规律）中的电磁透明现象。讨论了诱导透明效应和静电场的自发产生。我们特别关注了自感电磁透明及其与动态电子局域化的关系。研究了在外场作用下透明体的形成、崩塌和稳定的过程和机制。特别是，我们提出的超晶格电流在外部双谐场的时间演化的数值结果显示的主要渠道的透明度崩溃和其部分稳定的情况下，低电子密度超晶格。
英文摘要：
We examine phenomenon of electromagnetic transparency in semiconductor superlattices (having various miniband dispersion laws) in the presence of multi-frequency periodic and non-periodic electric fields. Effects of induced transparency and spontaneous generation of static fields are discussed. We paid a special attention on a self-induced electromagnetic transparency and its correlation to dynamic electron localization. Processes and mechanisms of the transparency formation, collapse, and stabilization in the presence of external fields are studied. In particular, we present the numerical results of the time evolution of the superlattice current in an external biharmonic field showing main channels of transparency collapse and its partial stabilization in the case of low electron density superlattices.
