Abstract

The superconducting transition temperature T_c of multilayers of electron-doped cuprates, composed of underdoped (or undoped) and overdoped La_2-xCe_xCuO₄ (LCCO) and Pr_2-xCe _xCuO₄ (PCCO) thin films, is found to increase significantly with respect to the T_c of the corresponding single-phase films. By investigating the critical current density of superlattices with different doping levels and layer thicknesses, we find that the T_c enhancement is caused by a redistribution of charge over an anomalously large distance.
