Imaging Coherent Nanoscale Strain Waves with Ultrafast Electron Microscopy
David Flannigan
Chemical Engineering and Materials Science, University of Minnesota
ABSTRACT: Flannigan works on the development and application of ultrafast electron imaging and diffraction. The interaction of light with materials is central to innumerable fundamental phenomena and technologies. Accordingly, it is highly desirable to formulate detailed, comprehensive descriptions of the electronic and structural responses between materials and light. Flannigan explains the capabilities of the ultrafast transmission electron microscopy (UEM) lab at the University of Minnesota and provides an overview of the ongoing work of his research group, which focuses on understanding high-velocity, coherent strain waves in nanoscale materials.
