Studies of Electronic Raman scattering in CdS/HgS cylindrical quantum dot quantum well structures

Electronic Raman scattering (ERS) is investigated in CdS/HgS cylindrical quantum dot quantum well. The ERS cross-section is calculated as a function of the frequency shift. The process involves an interband electronic transition and an intraband transition between quantized subbands. Different scattering configurations are discussed and the selection rules for the processes are also studied. Rich spectra are found and interpreted. The ERS studied here can be used to provide direct information about the electron band structure of these systems.
