Electrodynamic properties of an artificial heterostructured superconducting cuprate

A. Perucchi, P. Di Pietro, S. Lupi +6

We perform infrared conductivity measurements on a series of CaCuO${}_2$/SrTiO${}_3$ heterostructures made by the insulating cuprate CaCuO${}_2$ (CCO) and the insulating perovkite SrTiO$…
