Abstract

We study the effect of nonlinearity on the energy spectrum of a one-dimensional Kronig-Penney lattice of potential barriers and wells, consecutively. It is found for potential barriers that the bandgap either broadens or gets suppressed depending on the sign of the nonlinear interaction. This behavior is reversed if we consider a periodic system of potential wells. These features are explained with the help of a simple double barrier (or well) system.
