Nanoscale Domain Control in Multiferroic BiFeO3 Thin Films

A 1D periodic structure of ferroelectric domains in epitaxial BiFeO3 films is created. By careful control of the growth mechanism for the SrRuO3 bottom electrode, its in‐plane lattice parameters are confined by the underlying DyScO3 (110)O single‐ crystal substrate, enabling the formation of an expi...

Description
Summary:A 1D periodic structure of ferroelectric domains in epitaxial BiFeO3 films is created. By careful control of the growth mechanism for the SrRuO3 bottom electrode, its in‐plane lattice parameters are confined by the underlying DyScO3 (110)O single‐ crystal substrate, enabling the formation of an expitaxial film of (110)O SrRuO3 with a single structural domain (see figure).
