DOE SCIENCE NEWS BY TOPIC: Physical Sciences
DOE provides the majority (approximately 90%) of federal support for high-energy and nuclear physics research, which uses advanced accelerator facilities as well as detectors placed underground and in space to understand the fundamental nature of matter, energy, space, time and the properties and interactions of atomic nuclei and nuclear matter.

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.
