| Abstract: | small Electron Raman scattering (ERS) is investigated in aspherical HgS/CdS quantum dot quantum well (QDQW). The differentialcross section (DCS) is calculated as a function of the scatteringfrequency and the sizes of QDQW. Single parabolic conduction andvalence bands are assumed. The selection rules for the processes are studied. Singularities in the spectra are found andinterpreted. The ERS studied here can be used to provide directinformation about the electron band structure of these systems. |
