We present an evaluation for the calculation of the effective g-factor and the effective mass of conduction band electrons in pseudomorphic strained layers. We apply this evaluation to some important heterostructure systems and show that the effective mass is mainly isotropically shifted wheras the g-factor exhibits anisotropic splitting. We show that these effects, being attributed to the internal strains induced by lattice mismatch, may be used to characterize heterostructures.
