Title: Spectroscopy and dynamics of unoccupied electronic states of periodically rippled graphene
Jens Guedde was born in Berlin (Germany) and received a Ph.D. degree in physics in 1995 from the Free University of Berlin for work on high resolution laser spectroscopy of Rydberg atoms. After spending a year as a postdoc at the Max-Born-Institute for Nonlinear Optics and Short Pulse Spectroscopy in Berlin, he returned to the Free University of Berlin and worked on non-linear optics and ultrafast spin dynamics in thin metallic films. In 2000 he joined the surface science group of Prof. Dr. Ulrich Höfer at the Philipps-University in Marburg (Germany), where he started to study ultrafast electron dynamics at metal surfaces using two-photon photoemission and non-linear optical spectroscopy. For this work, he received his habilitation for experimental physics in 2006 and has now a permanent position in Marburg.
