DOE SCIENCE NEWS BY TOPIC: Engineering and Technology

DOE laboratories operate many of the nation’s most sophisticated research facilities, including the nation’s largest high performance computing centers, the world’s highest energy proton collider, third-generation synchrotron light sources and high-flux neutron sources as well as specialized facilities for microcharacterization, materials synthesis, combustion research, ion beam studies, and fusion energy research. The agency’s research facilities have an enormous impact on science and technology ranging from the most fundamental constituents of matter to superconductor structure and the production of unique isotopes for defense applications.

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.
