Abstract

In this paper we report the structure of voids in several thousand atom models of hydrogenated amorphous silicon. The models are produced by jointly employing experimental information from Smets and coworkers [1] and first principles simulations [2]. We demonstrate the existence of a useful correlation between the presence of large irreducible rings and the voids in hydrogenated amorphous silicon networks. Molecular hydrogen is observed in the models, and discussed.

An irreducible ring is said to be topologically degenerate when multiple paths of the same length exist that start and end at the same atomic site. Such rings are included in the distribution shown in figure 3L.Google Scholar
