Researchers find that polarization changes at the nanoscale

How small is too small to be useful? Researchers at North Carolina State University have done nanoscale analysis on ferroelectric thin films - materials that are used in electronic devices from computer memories to iPhones and polarize when exposed to an electric charge - and found that when it comes to polarization, both size and location matter.
