                         semiconductor quantum wells (AQWs) and its tuning with the 
                         structure parameters and composition are investigated with 
                         envelope-function theory and the 8 x 8k . p Kane model. The 
                         spin-dependent terms in the electron effective Hamiltonian in the 
                         presence of an external magnetic field are treated as a 
                         perturbation and the g factors g(perpendicular to)* and g(parallel

                         direction, are obtained analytically as a function of the well 
                         width L. The effects of the structure inversion asymmetry (SIA) on

                         SIA, which can explain recent measurements and be useful in 
                         spintronic applications. Specific results for narrow-gap 
                         AlSb/InAs/GaSb and AlxGa1-xAsGaAs/AlyGa1-yAs AQWs are presented 
                         and discussed with the available experimental data; in particular 
                         InAs QWs are shown to not only present much larger g factors but 
                         also a larger g-factor anisotropy, and with the opposite sign with 
                         respect to GaAs QWs.",
