Description
Summary:An amazingly simple model of correlated disorder is a one-dimensional chain of n potential steps with a fixed width ... and random heights. A theoretical analysis of the average transmission coefficient and Landauer resistance as functions of n and ... predicts two distinct regimes of behavior, one marked by extreme sensitivity and the other associated with exponential behavior of the resistance. The sensitivity arises in n and ... for ..., where the system is nearly transparent. Numerical simulations match the predictions well, and they suggest a strong motivation for experimental study.
