Welcome
The Electron Physics Group conducts wide ranging, cross-disciplinary research focusing on innovative measurement science in nanotechnology with an emphasis on applications for future electronics. The Group’s current expertise includes scanning probe microscopy and spectroscopy, nanoscale magnetic imaging and dynamics, the theory of magnetism and electronic structure, and laser-based atom manipulation. These capabilities are put to use in research programs that support development of new paradigms in nanoelectronics, examining such areas as transport in novel electronic materials (e.g. graphene), spintronic and other nanomagnetic data storage and processing devices, and focused ion beam imaging and fabrication. This research is built on the Electron Physics Group’s rich history of influential research and world-leading instrumentation development in spin-polarized electrons, electron-surface interactions, electron-atom scattering, electron optics and electron microscopy and spectroscopy.
