News From the Field
Caltech Scientists Film Photons With Electrons

December 16, 2009

4D electron microscopy Techniques recently invented by researchers at the California Institute of Technology--which allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter--have been used to image the evanescent electrical fields produced by the interaction of electrons and photons, and to track changes in atomic-scale structures. Papers describing the novel technologies appear in the Dec. 17 issue of the journal Nature and the Oct. 30 issue of Science. Full Story
