Experimental Studies of the Dynamics of Electrons in Disordered Metals

这项研究是对无序金属中电子动力学的研究，其中电学性质主要由量子力学干涉效应决定。其目的是在测量频率大于量子退相率的情况下，对电导随频率变化的情况有一个了解。无序的二维和三维样品以及亚微米样品。电导和电感的测量范围从直流到20千兆赫的频率，温度到0.02开尔文，以及高达10特斯拉的磁场。样品的成分和几何形状也将有所不同。除了在量子输运研究中增加一个新的实验参数的确定之外，这些研究对于介观系统的技术也是一个重要的领域。

This research represents an investigation of the dynamics of electrons in disordered metals where the electrical properties are determined primarily by quantum mechanical interference effects. The objective is to reach an understanding of the frequency- dependent conductance in the regime where the measurement frequency is greater than the quantum dephasing rate. Disordered two- and three-dimensional samples and also submicron samples. The electrical conductance and susceptance will be measured for frequencies from dc to 20 GigaHertz, for temperatures down to 0.02 Kelvin, and for magnetic fields up to 10 tesla. The sample composition and geometry will also be varied. In addition to adding the determination of a new experimental parameter in the study of quantum transport these studies are in an important regime for the technology of mesoscopic systems.
