Infrared properties of single crystal MgO, a substrate for high temperature superconducting films
Abstract
An extended analysis of the infrared properties of single crystal MgO, an important substrate for high-Tc superconducting films, has been performed, measuring transmission spectra over 15-280 per cm at temperatures between 20 and 290 K. Spectra over 40-280 per cm were measured using the infrared beam line at the National Synchroton Light Source (NSLS) 0.75 GeV storage ring located at Brookhaven National Laboratory. Measurements from 15-40 per cm were performed at Emory University using a spectrometer optimized for low frequencies. The NSLS and Emory data matched within 1 percent.
