James E. Wittig

Associate Professor of Materials Science and Engineering
Associate Professor of Electrical Engineering


Professor Wittig utilizes analytical and high resolution electron microscopy for materials characterization in order to develop structure-property relationships. Areas of interest include magnetic thin films for data storage and advanced structural materials. Further increases in the areal density for magnetic data storage will require new materials that can decrease the size of individual magnetic grains in the thin films. To develop the processing methods for growing these nanometer size features demands materials characterization with atomic resolution. Access to the world’s most powerful electron microscopes at the Ernst-Ruska Center in Jülich Germany and the National Center for Electron Microscopy at the Lawrence Berkeley Laboratory provides the sub-angstrom resolution required for this nanoscale research.
