High-temperature superconducting thin films and the mechanism of superconductivity
High-temperature superconductors predominantly exhibit layered lattice structures,and thus the study of epitaxial thin films and heterostructures,which inherently possess low-dimensional properties,has become a major method for exploring the mechanism of superconductivity.In recent years,the development of atomically precise epitaxy has further facilitated the discovery of novel superconductors.This article will follow a dimensionality reduction trajectory to explore the unique contributions of high-temperature superconducting thin films and heterostructures in deepening our understanding of the mechanism underlying superconductivity.
