NATIONAL LABORATORY

ORNL is a multiprogram science and technology laboratory managed for the U.S. Department of Energy by UT-Battelle, LLC. Scientists and engineers at ORNL conduct basic and applied research and development to create scientific knowledge solutions that strengthen the nation's leadership in key areas of science; increase the availability of clean, abundant energy; restore and protect the environment; and contribute to national security.

ORNL also performs other work for the Department of Energy, including isotope production, information management, and technical program management, and provides research and technical assistance to other organizations.

Materials scientists play atomic 'Jenga' and make a surprising discovery

Materials scientists play atomic 'Jenga' and make a surprising discovery

Researchers got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra 'switch' that brings functionalities to materials when 'flipped' by external stimuli. The material defects induced polar behavior and can provide a new mechanism for manipulating electricity and magnetism in energy and information technologies.
