Time-resolved photoelectron emission from surfaces

The attosecond streaking technique provides a unique tool to study the motion of particles with unprecedented accuracy. While originally developed for investigations of atomic systems streaking is now also applied to condensed-matter systems. We have developed a model to simulate the motion of electrons under the combined influences of crystal atoms, other target electrons, and the external pump and streaking fields. Good agreement between this semiclassical model and experimental results is reached.
