Basic features of confined excitons with strongest transitions between electron and hole states of equal principal quantum numbers remain similar. The three

Avdeeve ferromagnetic and antiferromagnetic regimes at lower temperature..The spin of carriers is utilized in spintronics for current control by creating a nonequilibrium spin polarization. When phase effects can be neglected, the transport of spin-polarized carriers is described by a two-current model as
