Low Temperature Electronic Properties of Conducting Solids

这个项目是一个为期三年的实验研究项目，旨在了解超导体中弱耦合效应的性质，重点是维度效应、涡旋动力学和非线性输运。计划进行两类实验。第一个涉及层状高温超导体中涡线和约瑟夫森涡的层间耦合和动力学测量。第二类涉及非均匀非线性超导介质的输运和无线电频谱响应测量，包括二维颗粒复合薄膜和约瑟夫森结阵列的相位相关和波动的测量。本项目分为高温超导体电子特性实验基础研究和超导隧道结微电路阵列特性实验基础研究两部分。在第一个项目中，研究将探索高温超导体对磁场的响应，最终目的是解释决定其技术和科学适用性的潜在物理原理。第二个项目将研究超导隧道结的微电路，部分是为了阐明基本的物理原理，部分是为了确定在需要极高灵敏度的电子应用中的潜在用途。＊＊＊

9501272 Garland This project is a three-year program of experimental research directed at understanding the properties of weak coupling effects in superconductors, with an emphasis on dimensionality effects, vortex dynamics, and non-linear transport. Two categories of experiments are planned. The first involves measurements of interlayer coupling and dynamics of vortex lines and Jospphson vortices in layered high temperature superconductors. The second category involves transport and radio frequency spectral response measurements of inhomogeneous non-linear superconducting media, including measurements of two- dimensional granular composite films and of phase correlations and fluctuations in Josephson junction arrays. %%% This project is a two-part program of experimental basic research on the electronic properties of high temperature superconductors, and also on the properties of microcircuit arrays of superconducting tunnel junctions. In the first project, the research will explore the response of high temperature superconductors to magnetic fields, with the ultimate foal of explaining the underlying physical principles that determine their technical and scientific applicability. The second project will investigate microcircuits of superconducting tunnel junctions, in part to elucidate fundamental physical principles and in part to determine the potential usefulness in electronics applications that require extreme sensitivity. ***
