Abstract
The thermal fluctuations in electric field and vibrational amplitude associated with optical surface phonons in dielectric spheres are derived and compared with the corresponding bulk-phonon fluctuations. Expressions for the Raman scattering efficiencies of bulk and surface phonons in very small spherical crystals are obtained, and numerical results for the case of GaP are presented.Keywords
