Résumé : The intrinsic spin Hall conductivity is calculated for a two-dimensional electronic gas (2DEG) in presence of strain, Rashba coupling, and an external in-plane applied magnetic field. The conduction electrons of [001] oriented quantum well (QW) are used to model the 2DEG. For a stress applied in the growth direction of QW the intrinsic dc spin Hall conductivity is not dependent on the strain and the in-plan applied magnetic field, and it has the universal value $e∕8\ensuremath{\pi}$.
