Sondhauss, Peter LU ; Harbst, Michael LU ; Larsson, J.; Naylor, G.A.; Plech, A.; Scheidt, K.; Synnergren, Ola LU ; Wark, J.S. and Wulf, M. (2004) Eighth International Conference on Synchrotron Radiation Instrumentation In AIP Conference Proceedings 705. p.1387-1390
Abstract
Atomic processes like e.g. molecular vibrations, chemical reactions or phase transitions happen on picosecond down to femtosecond time scales. Novel pulsed X-ray sources or alternatively ultrafast X-ray detectors allow the investigation of these processes in real time. A powerful tool for the investigation of the dynamics in crystalline materials is time resolved X-ray diffraction (TRXD). As an example the authors present the measurement of "phonon branch folding" in a GaSb/InAs superlattice by means of TRXD. In the second part we look forward to the near future of TRXD. X-ray scattering from coherent acoustic and optical phonons has recently become describable within the framework of dynamical diffraction theory. This theory provides the... (More)
