Glancing angle deposition for tuning electronic transport properties of Si thin films
Résumé
In this work, we developed a one-dimensional tight-binding model to study conductivity in solid-state superlattices. We investigated the localization properties of a tight-binding equation where the on-site potential is replaced by both quasiperiodic and periodic
functions. We compared the metal–insulator transitions obtained using a periodic potential with an external electric field and an Aubry–André potential, which is the only known case of a 1D model with a mobility edge. For the case of a periodic potential, we
found the existence of a similar mobility edge if the applied electric field is small enough. In such a case, the extended and localized states in the superlattice can be controlled by an external source.
