Superconducting properties of epitaxial ultrathin ReBa2Cu3O7-δ (ReBCO) (Re = Rare earth) films sandwiched between (PrxY1-x)Ba2Cu3O7-δ ((PrxY1-x)BCO) (0≤x≤1) layers and ReBCO/(PrxY1-x)BCO superlattices have been studied with varying thicknesses of ReBCO and doping level x in the adjacent (PrxY1-x)BCO layers. While various experiments have been performed in these systems, in this paper, we will primarily focus on the results of superconducting properties of the ultrathin films and superlattices, the dependence of the superconductivity on adjacent layer materials, and the possibility of charge redistribution across the interface.
