摘要：
Electron Raman scattering (ERS) is investigated in a CdS cylindrical spherical dot (QD). The different cross-section (DCS) is calculated as a function of the scattering frequency and the size of QD. Single parabolic conduction and valence bands are assumed. Singularities in the spectrum are found and interpreted. The selection rules for the processes are also studied. The ERS studied here can be used to provide direct information about the electron band structure of these systems.
