    • Studied physics at the University of Tübingen. After receiving his Vordiplom, he was granted a Fulbright fellowship to study physics at the Graduate School of Brown University, Providence, Rhode Island, where he obtained an Sc.M. in both electrical engineering (1984) and physics (1985) as well as a Ph.D in physics (1986). At Brown he remained as a postdoc until 1987, working on time-resolved acoustic-phonon spectroscopy in amorphous and crystalline solids. Since 1987 he has been working at the Max-Planck-Institut für Festkörperforschung in Stuttgart in the group of Manuel Cardona, where he holds a staff position. His current research activities lie in Raman scattering in high-Tc superconductors and the investigation of electron-phonon coupling in these materials. He completed his habilitation at the Technical University of München in 1991. Also in 1991 he received the Walter-Schoctky-Prize for his contributions to the understanding of high-Tc superconductivity.

Abstract

The non-destructive analysis of superconductors is made possible by Raman scattering techniques. A number of fundamental properties can be examined due to the coupling of electronic system of the materials with the phonons which are actually measured in Raman scattering, including the superconducting energy gap and the Fermi velocity. The aspects of materials characterization are reviewed and the insight and which Raman scattering experiments offer into electron-phonon coupling discussed.
