In this work, by using the particle swarm optimization the electron Raman scattering for square double quantum wells is optimized. For this purpose, by combining the particle swarm algorithm together with the numerical solution procedures for equations, and also the perturbation theory we find the optimal structure that maximizes the electron Raman scattering. Application of this algorithm to the structure of asymmetric double quantum wells shows that the differential cross section of an electron Raman scattering is 1.30390×10⁵ Arb.Units.
