  • Thursday March 26, 2009 at noon in conference Room 432C
    Agenda: 
    Introduction and Announcements.  
    Investigation of fast processes in condensed matter by time-resolved x-ray diffraction (APS access only)
    Ingo Uschmann, University of Jena Abstract New results for fs-laser excited semiconductor crystals probed by ultrashort x-ray pulses excited by a laser produced x-ray plasma-source will be presented.Contribution of fast electronic response, such as electronic pressure and electron diffusion as well as relaxation of the excited semiconductor, such as Ge and InSb will be discuss and compared to simulations. Further the temporal evolution of the laser induced metal-semiconductor phase transition, probed by optical reflectometry and x-ray diffraction of the rare earth compound samarium sulphide will be presented and discussed.
