Spatially and momentum resolved electronic transport trough metal films using the Boltzmann Transport Equation — •Mourad El Kharrazi1, Orkhan Osmani1,2, Bärbel Rethfeld2, and Marika Schleberger11University of Duisburg-Essen, Germany — 2Technical University of Kaiserslautern, Germany

After the electronic excitation of a thin metal film, by e.g. laser or highly charged ion impact, the electronic system of the metal possesses high kinetic energy. Transport processes dissipate this excitation energy into the material. The hot electrons equilibrate at the same time to a new equilibrium distribution. These mechanisms can be described via a spatially and momentum resolved Boltzmann Transport Equation. We present results on both the transport inducing a momentum-dependent nonequilibrium distribution as well as the collisional processes of hot electrons.
