Growth Of Yba2cu3o7-Δ Thin-Films–Nucleation, Heteroepitaxy And Interfaces, M. Grant Norton, C. Barry Carter

Scanning Microscopy

A major research effort in high-temperature oxide superconductors is the growth of high-quality thin-films. The physical properties of polycrystalline thin-films are controlled by their microstructure which is influenced by the early stages of film growth and the establishment of epitaxy. In this article, the nucleation and heteroepitactic growth of YBa₂Cu₃O_7-δ thin-films is reviewed. Many of the examples illustrating film growth will be taken from studies using transmission electron microscopy. The importance of the substrate surface in controlling film growth will be discussed, in particular the growth of YBa₂Cu₃O_7-δ films on …
