Abstract

Structural compliance is the ability of a crystal structure to accommodate variations in local atomic bond lengths without incurring large strain energies. We show that the structural compliance of cuprates is relatively small, so that the short, highly doped, Cu-O-Cu bonds in stripes are subject to a tensile misfit strain. We develop a model to describe the effect of misfit strain on charge ordering in the copper-oxygen planes of oxide materials and illustrate some of the low-energy stripe nanostructures that can result.
