Correlation and Localization in 2D and 3D Electron Systems

将研究相互作用的电子气体系统的远红外线磁光和磁输运研究。本研究的重点将是基于砷化镓铝异质结构外延生长的宽抛物阱结构的准三维（Q3D）电子气体。这项研究包括对这些系统中的Q3D磁等离子体激元的研究，最终目标是发现维格纳晶体。该计划还包括研究二维电子气体系统中的磁等离子体，因为磁质子与分数量子霍尔效应有关。本文还将研究掺杂砷化镓中硅的上哈伯德能带的平衡性质，以及二维掺杂砷化镓中杂质能带的形成。

Far infrared magneto-optical and magneto-transport studies of interacting electron gas systems will be investigated. The main thrust of this research will be on quasi-3 dimensional (Q3D) electron gas based on wide parabolic well structures grown epitaxially with gallium-aluminum arsenide heterostructures. The research involves the study of Q3D magneto-plasmons in these systems with the ultimate goal being the discovery of the Wigner crystal. The plans also include the study of magneto-plasmons in the two-dimensional electron gas system because of magneto-rotons associated with the fractional quantum Hall effect. The equilibrium properties of the upper Hubbard band for silicon in doped gallium arsenide will also be studied, as will impurity band formation in two-dimensional delta-doped gallium arsenide.
