The differential cross section (DCS) for exciton-mediated Raman scattering (EMRS) in one-dimensional semiconductor quantum dots is presented. The exciton states are considered as intermediate states in the Raman scattering process. The selection rules for the EMRS process are studied. The numerical results show that the contribution to DCS indicated by exciton is larger than that by electron. DCS of EMRS is larger when there is a bigger confinement potential frequency.

We develop a model appropriate for describing the Raman spectrum of samples, containing a collection of semiconductor quantum dots with and without dispersion in their linear dimensions. These nanometer size crystallites are assumed to have the same atomic arrangement as that of the bulk material and to be embedded in a host material made up of a different semiconductor of the same crystal structure. The results from our calculations are compared to previous models for polycrystalline materials.
