Competing Misfit Relaxation Mechanisms in Epitaxial Correlated Oxides
Competing Misfit Relaxation Mechanisms in Epitaxial Correlated Oxides
Strain engineering of functional properties in epitaxial thin films of strongly correlated oxides exhibiting octahedral-framework structures is hindered by the lack of adequate misfit relaxation models. Here we present unreported experimental evidence of a four-stage hierarchical development of octahedral-framework perturbations resulting from a progressive imbalance between electronic, elastic, and octahedral …
