Magnetic field effects on the electron Raman scattering in coaxial cylindrical quantum well wires

Based on the effective mass and parabolic one band approximations, the influence of an external magnetic field on the differential cross-section for the intersubband electron Raman scattering process in coaxial cylindrical quantum well wires is investigated. The dependence of differential cross-section on magnetic field strength and structural parameters of the coaxial cylindrical quantum well wire is studied. It is found that the magnetic field strength and the geometrical size of the system have a great influence on the position of the singularities in the emission spectra. Moreover, one can control the frequency shift in the Raman spectrum by varying the magnetic field strength and the size of the coaxial cylindrical quantum well wire. •Magnetic field effects on ERS in CCQWWs are investigated.•Light polarization vectors and geometrical size effects on the ERS are also studied.•Number, position and magnitude of the peaks depend on the magnetic field strength.•The light polarization vectors have a great influence on the magnitude of the peaks.•An increase in the size leads to the considerable changes in the emission spectra.
