摘要：
We present theoretical results concerning the electron Raman scattering process related to the longitudinal optical (LO) phonon modes in a two - dimensional quantum pseudo - dot, under the influence of a uniform magnetic field. The Frohlich electron - phonon interaction for resonance Raman scattering is considered. External magnetic field, the geometrical size of the pseudo - dot and the electron - phonon interaction effects on the differential cross section of the Raman scattering are investigated. Our Results reveal that the geometrical parameters of the pseudo - dot as well as the external magnetic field and electron phonon interaction have a great influence on the position and the magnitude of the peaks of the emission spectra.
