On-demand nanoengineering of in-plane ferroelectric topologies
Posted by Omuterema Akhahenda in category: engineering
Hierarchical assemblies of ferroelectric nanodomains, so-called super-domains, can exhibit exotic morphologies that lead to distinct behaviours. Controlling these super-domains reliably is critical for realizing states with desired functional properties.
A biased atomic force microscopy tip can write complex in-plane polar topologies in a model ferroelectric Pb0.6Sr0.4TiO3 by means of a smart scan path design. Hence, on-demand generation, reading and erasing of tunable topologies is possible.
