Exciton and confinement potential effects on the resonant Raman   scattering in quantum dots
  Resonant Raman scattering in semiconductor quantum dots with spherical shape is theoretically investigated. The Frohlich-like interaction between electronic states and optical vibrations has been considered. The Raman profiles are studied for the following intermediate electronic state models: (I) Uncorrelated electron-hole pairs in the strong size quantized regime, (II) Wannier-Mott excitons in an infinite potential well, and (III) Excitons in a finite confinement barrier. It is shown that the finite confinement barrier height and the electron-hole correlation determine the absolutes values of the scattering intensities and substantially modify the Raman line shape, even in the strong confinement regime.
