Band structure of compensated n-i-p-i superlattices.

The band structure of compensated n-i-p-i doping superlattices has been investigated for the first time by using the multistep-potential approach as the real potential form and by using numerical calculations. The dispersion of compensated n-i-p-i superlattices is shown to be stronger than that of compositional superlattices. The Srst three allowed conduction minibands and forbidden rninigaps as functions of period length L are presented.
