I'm studying periodic boundaries in 1D for which energy gaps occur, i.e. values of the energy which are not allowed, according to the Kronig-Penney model. My question is when these band gaps occur what happens to the wave-function, because it still has to be continuous, so it can't just terminate, so does it stay the same? Or what happens to the wave-function at these regions?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks!
