How Small is Too Small? Researchers Find that Polarization Changes at the Nanoscale

(PhysOrg.com) -- 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.
