Infrared Properties of Oxide Superconductors

本文研究了生长和人工结构高温超导体在远红外到紫外波段的光学特性。通过测量钇-钡-铜/镨-钡-铜多层体系，研究超导层厚度和层间耦合的作用。对各种其他高温超导体材料的测量将解决诸如超导能隙和中红外范围内发生的非德鲁德吸收的性质等问题。该项目代表了佛罗里达大学和贝尔通信研究之间的合作，佛罗里达大学将进行大部分红外测量，贝尔通信研究将进行大部分样品制备。

This research is concerned with a study of the optical properties of as-grown and artificially-structured high-temperature superconductors over the far-infrared through ultraviolet wavelength range. The role of the superconducting layer thickness and of interlayer coupling will be studied through measurements of yttrium-barium-cuprate/praseodymium-barium-cuprate multilayer systems. Measurements of a wide variety of other high temperature superconductor materials will address issues such as the superconducting energy gap and the nature of the non-Drude absorption that occurs in the midinfrared range. The project represents a collaboration between the University of Florida, where most of the infrared measurements will be made, and Bell Communications Research, where much of the sample preparation will be carried out.
