Abstract
We study the transmission problem for electrons in an alternately linear-non-linear medium using a quasiperiodic Kronig-Penney model whose variance in spatial locations obeys the Fibonacci rules. We find that for waves with low intensity and long wavelength, non-linearity enhances the lattice transparency.Keywords
