Brookhaven scientists used a technique called electron holography to capture images of the electric fields created by the materials’ atomic displacement with picometer precision — that’s the trillionths-of-a-meter scale crucial to understanding these promising nanoparticles. By applying different levels of electricity and adjusting the temperature of the samples, researchers demonstrated a method for identifying and describing the behavior and stability of ferroelectrics at the smallest-ever scale, with major implications for data storage.

The boundary between electronics and biology is blurring with the first detection by researchers at Department of Energy's Oak Ridge National Laboratory of ferroelectric properties in an amino acid called glycine.

If solar cells could generate higher voltages when sunlight falls on them, they’d produce more electrical power more efficiently. For over half a century scientists have known that ferroelectrics, materials whose atomic structure allows them to have an overall electrical polarization, can develop very high photovoltages under illumination. Until now, no one has figured out exactly how this photovoltaic process occurs.
