Abstract

Disordered semiconductors are in common use due to their wide range of applications, however, a comprehensive model describing their charge transfer remains elusive. One challenge in developing such a model arises due to the non-crystalline nature of these materials, but another, more complex, hurdle to overcome is accounting for the various competing transport mechanisms at play. One example of such materials, known as electron glasses, provide a useful basis for study since they are relatively easy to prepare and measure experimentally.

One downside of studying such materials is that they are among the most complex and therefore least understood systems in terms of underlying physics. Owing to this complexity, which includes the need to consider all possible transitions occurring simultaneously, equilibrium-based simulations cannot be directly employed. Presented is a potential alternative method that aims to derive an advantage from this overlapping complexity in that it may be possible to employ relative low-cost equilibrium-based methods if the system is appropriately over-defined.
