Physics of Two-Dimensional Electron Systems

这个实验研究项目涉及凝聚态物质最基本的量子力学性质，在低温和高磁场下以优雅的方式进行探测。得到的结果对先进理论的表述和证实很有兴趣，这些理论本身可能适用于其他现象，如高温超导，这些现象仍然知之甚少。更具体地说，二维和大小量子化系统的集体基态的性质将被研究的少和强相关电子。特别的主题包括整数和分数量子霍尔效应，相关的一维边缘态，维格纳结晶和单电荷载流子隧道现象。实验方法包括磁输运、热激活、非线性输运、共振和单粒子隧穿，在低温和高磁场下进行。这个实验研究项目是关于凝聚态物质的最基本的量子力学性质，在低温和高磁场下以优雅的方式进行探测。得到的结果对先进理论的表述和证实很有兴趣，这些理论本身可能适用于其他现象，如高温超导，这些现象仍然知之甚少。更具体地说，二维和大小量子化系统的集体基态的性质将被研究的少和强相关电子。特别的主题包括整数和分数量子霍尔效应，相关的一维边缘态，维格纳结晶和单电荷载流子隧道现象。实验方法包括磁输运，热活化，非线性输运，共振和单粒子隧道，在低温和高磁场下进行。＊＊＊

w:\awards\awards96\*.doc 9629851 Goldman This experimental research project is concerned with the most fundamental quantum mechanical properties of condensed matter probed in an elegant fashion at low temperature and high magnetic field. The results to be obtained are of interest in the formulation and confirmation of advanced theory, which itself may apply to other phenomena such as high temperature superconductivity, which remain poorly understood. More specifically, the properties of the collective ground states of two-dimensional and size-quantized systems of few and strongly correlated electrons will be studied. Particular topics include integer and fractional quantum Hall effects, the associated one- dimensional edge states, Wigner crystallization and single-charge carrier tunneling phenomena. Experimental methods include magnetotransport, thermal activation, nonlinear transport, and resonant and single-particle tunneling, performed at low temperature and high magnetic field. %%% This experimental research project is concerned with the most fundamental quantum mechanical properties of condensed matter probed in an elegant fashion at low temperature and high magnetic field.
