Laserinduced heating of thin graphite and SAM-graphene monitored by Ultrafst Electron Diffration — •Silvio Morgenstern, Christian Gerbig, Cristian Sarpe, Matthias Wollenhaupt, and Thomas Baumert — Universität Kassel, Institut für Physik und Center of Interdisciplinary Nanostructure Science and Technology (CINSaT), D-34132 Kassel, Germany

Ultrafast Electron Diffraction (UED) has lately become one of the most promising techniques to directly provide insights into fundamental dynamics in solids at the microscopic level on the pico- to subpicosecond timescale [1,2].

In this contribution we present our UED-setup to reach a high spatial and temporal resolution. Additionally we present first results in time-resolved diffraction experiments on thin graphite and SAM-graphene [3] and compare these with results from CVD-graphene [4].
