摘要：

A way of modulating superlattice band structure is presented utilizing a delta-doping technique. Enormous changes in the electronic states of a superlattice can be made by introducing spatially localized defects with a periodic array in the well layers as well as in the barrier layers of a superlattice. Along with an analytic energy dispersion relation, it is shown that the creation of a band or the annihilation of a given band and the control on the miniband gap, band positions, and their widths are now possible by adjusting the weight and the position of the inserted defects.
