High Temperature Cuprate-Like Superconductivity at Surfaces and Interfaces

TL;DR

This paper discusses the occurrence of high-temperature superconductivity at surfaces and interfaces, emphasizing the relevance of a self-organized percolative model in quasi-two-dimensional systems for understanding these phenomena.

Contribution

It extends the percolative self-organized model of bulk HTSC to describe high-temperature superconductivity at surfaces, interfaces, and nanoscale clusters.

Findings

HTSC can occur at free surfaces and interfaces.

The self-organized percolative model applies to quasi-two-dimensional HTSC.

The model explains HTSC phenomena in reduced dimensions.

Abstract

The realization of high-transition-temperature superconductivity (HTSC) confined to nanometre-sized interfaces has been a long-standing goal because of potential applications and the opportunity to study quantum phenomena in reduced dimensions. Here we discuss HTSC at free surfaces, interfaces, and nanoscale cluster surfaces, and show that the percolative self-organized model of bulk HTSC also gives an excellent description of HTSC in quasi-two-dimensional contexts.
