Longitudinal and transverse spin diffusion coefficients are calculated with the quantum transport equation which includes many-particle effects in the random phase approximation. We find that the $e$-$e$ scattering, which does not contribute to charge drift mobility, has a significant contribution to the spin diffusion. Thus, $e$-$e$ interaction causes non-negligible effects on the operations of proposed devices dependent on spin transport in semiconductor heterostructures.16pages including 5 figures, single columnMesoscale and Nanoscale PhysicsMaterials Sciencetext
