The strong contribution of the substrate to the reflectance of superconducting thin films prevents the use of standard Kramers-Krönig transformations to derive the superconductor optical conductivity. This quantity has to be obtained by canonical procedures, which imply the knowledge of the substrate optical conductivity. Two systems are discussed: a metallic BSCCO thin film deposited on MgO and an insulating one on ZrO2.

Abstract
The strong contribution of the substrate to the reflectance of superconducting thin films prevents the use of standard Kramers-Krönig transformations to derive the superconductor optical conductivity. This quantity has to be obtained by canonical procedures, which imply the knowledge of the substrate optical conductivity. Two systems are discussed: a metallic BSCCO thin film deposited on MgO and an insulating one on ZrO2.File in questo prodotto:
