Dopant size effects on novel functionalities: High-temperature interfacial superconductivity.

ABSTRACT: Among the range of complex interactions, especially at the interfaces of epitaxial oxide systems, contributing to the occurrence of intriguing effects, a predominant role is played by the local structural parameters. In this study, oxide molecular beam epitaxy grown lanthanum cuprate-based bilayers (consisting of a metallic (M) and an insulating phase (I)), in which high-temperature superconductivity arises as a consequence of interface effects, are considered. With the aim of assessing the role of the dopant size on local crystal structure and chemistry, and on the interface functionalities, different dopants (Ca²⁺, Sr²⁺ and, Ba²⁺) are employed in the M-phase, and the M-I bilayers are investigated by complementary techniques, including spherical-aberration
