Abstract

Raman spectroscopy with cw lasers in the visible, near ir and near uv is one of the most precise techniques to investigate low frequency elementary excitations in solids. It is particularly suitable for determining quasiparticle renormalizations due to small perturbations. The technique will be illustrated with examples for conventional semiconductors (effects of isotopic mass changes and fluctuations on phonon frequencies and line widths, effect of doping on same parameters) and high-Tc superconductors (effect of superconducting gaps on phonon frequencies and line widths, effect of crystal field transitions of the rare earth atoms on phonon frequencies and line shapes).
