摘要: Recent infrared reflectance spectroscopy on high quality crystals of a number HTSC systems shows thatall have finite conductivity in the frequency region superconducting gap. Results untwinned YBCO from laboratories show that this absorption is not due to experimental problems or sample-to-sample variations. Other materials also features gap form peaks. We discuss these results terms recent ideas effect impurities d-wave superconductors.
