A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices.

In oxide superlattices, the combined effect of strain and interlayer electrostatic interactions enables the stabilization of exotic polar topologies. Yet, their collective role in the mechanical response of the system remains largely unexplored. Here, we show that a high density of polar textures forms an elastically c...
