摘要/Abstract

摘要： The differential cross-section for electronic Raman scattering in double semi-parabolic quantum wells of typical GaAs/Al_xGa_1-xAs is investigated numerically with the effective-mass approximation. The dependence of the differential cross-section on structural parameters such as the barrier width and the well widths are studied. Our results indicate that the electronic Raman scattering is affected by the geometrical size and can be negligible in the symmetric double-well case.
