This
activity supports basic research in
condensed matter physics and materials physics using electron diffraction
and microscopy and scanning probe techniques. Research includes
experiments and theory to understand the atomic, electronic and magnetic
structures of materials, structural evolutions, and the
relationship of structure to the properties of materials.
Increasingly important are the nanoscale structures and the structure and
composition of inhomogeneities including defects, interfaces, surfaces,
and precipitates. Advancing the state of the art of electron beam and
scanning probe techniques and instrumentation for quantitative microscopy
and microanalysis is an essential element in this portfolio. This activity is driven by the need for quantitative characterization and understanding of materials structure and its evolution over atomic to micron length scales. It is a major source of research in the U.S. that is focused on structure and defects in atomic configurations over all length scales and dimensionalities, and is the nation’s primary investment in large-scale, comprehensive microscopy research groups which bring together science-driven investigators whose focus is the development and implementation of a wide variety of electron scattering and scanning probe techniques. The portfolio includes characterization and analysis of materials by transmission and scanning transmission electron microscopy, atom-probe field ion microscopy, scanning probe microscopies, spin polarized low energy electron microscopy, electron beam holography and tomography, convergent beam electron diffraction, ultrafast electron diffraction and microscopy and other state of the art methods. Research results are increasingly coupled with first-principles theory, which offers quantitative insights into the atomic origins of materials properties. Contractors' Meetings in the area of Electron and Scanning Probe Microscopies were held October 26-29, 2008 and October 29 - November 1, 2006. The abstracts are available on the web, here for the 2008 meeting and here for the 2006 meeting. The abstracts can also be accessed by clicking on either meeting's cover page on the left.
