                         engineering and spintronic applications, we investigate the

                         tunnelcoupled semiconductor quantum wells (QWs). Since the 
                         g-factor anisotropy sign change in narrow wells is due to SIA and 
                         determined by the electron average position, in double QW 
                         structures the quantum tunneling effect plays a pivotal role 
                         established by the central barrier length, which stands for the 
                         coupling parameter between the wells. Due to the quantum

                         perturbation theory, the corresponding components of the electron
