                         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 
                         to)*, for the magnetic field in the QW plane and along the growth 
                         direction, are obtained analytically as a function of the well 
                         width L. The effects of the structure inversion asymmetry (SIA) on 
                         the electron g factor are analyzed. For the g-factor main 
                         anisotropy Delta g = g(perpendicular to)*-g(parallel to)*. in 
                         AQWs, a sign change is predicted in the narrow well limit due to 
                         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.",
