Abstract

The effect of structural disorder under bias voltage on the transmission properties of a non-interacting electron across multibarrier systems (GaAs/AlxGa$_{1-x}$As) is exhaustively studied by a computational model using exact Airy function formalism and the transfer-matrix technique. In ordered systems we study the effect of bias voltage on miniband structure. For disordered structures we investigate the transmission coefficient. Different types of eigenstates are obtained, those having a very low Lyapunov exponent close to the resonant energy and those with high slope in other region. Commuting resonance energy is theoretically demonstrated in this paper, the obtained values are in good agreement with the existing numerical results.
