Imaging and Controlling Energy and Charge Transfer in Nanostructured Materials
Abstract
The objective of this work is the further development of 4D electron microscopy and diffraction for the studies of the structural dynamics of nanoscale materials and the transient structures of complex surfaces following ultrafast optical or heat excitation. Models that describe the evolution of structural dynamics from a microscopic atomic description to the nanoscale and on to macroscopic observations will be developed. These studies will improve our understanding of the dynamics and the nature of forces involved in nonequilibrium phenomena such as diffusionless charge transport, structural changes, friction at interfaces, and nucleation in melting.
