Abstract
Based on the effective mass and parabolic one-band approximations, the differential cross-section for the intersubband electron Raman scattering process in a single and multilayered spherical quantum dots is investigated. The influence of an on-center hydrogenic impurity and geometrical parameters such as the well and barrier widths on the differential cross-section is studied. Results show that the number, the position and the magnitude of the peaks of emission spectra, considerably depend on the presence of the hydrogenic impurity as well as geometrical parameters. Results also reveal that the magnitude of the peaks significantly depend on the polarization vectors of incident and scattered lights. • Hydrogenic impurity effects on ERS in single and multilayered SQDs are investigated. • Light polarization vectors and geometrical size effects the ERS are also studied. • Number, position and magnitude of the peaks, depend on the presence of the impurity. • The light polarization vectors have a great influence on the magnitude of the peaks. • Geometrical parameters considerably change the peaks number, position and magnitude.
