II Surface and Size Effects on the Light Scattering Spectra of Solids

摘要: Publisher Summary This chapter discusses the surface and size effects on light scattering spectra of solids recent developments, with emphasis certain theoretical methods that have proved useful to those engaged in research area. The also describes experimental studies effects. development a variety laser sources highly sophisticated spectrometers has enabled Raman spectroscopy become tool major importance arsenal solid state physics community. Until past few years, method been used primarily study elementary excitations characteristic infinitely extended medium. In addition, explains substantial body literature these waves, which propagate surfaces along interfaces, standing wave or guided modes free films substrates, finally inhomogeneities subtle features near spatial extent very much smaller than wavelength light.
