Title: Longitudinal effective mass and band structure of quasiperiodic Fibonacci superlattices

Abstract: A systematic study of the longitudinal effective mass associated with either shallow impurity states or conduction Landau levels under in-plane magnetic fields is presented for Fibonacci superlattices. We analyze the relation between the mean longitudinal effective masses and the localization length of the corresponding electronic or impurity states. Under appropriate conditions we show that the mean longitudinal effective mass weakly depends on the nature of the electron state and localization length, and is essentially related to the Canter-like energy spectra or 'band structure.'
