Microstructural analysis of nanoporous paracrystalline atomistic models of amorphous silicon

Microstructural analysis of nanostructured amorphous silicon–germanium alloys: Numerical modeling

“…4 shows the results of our calculations for the alloy composition x = 0.5 only, but the same behavior holds for the other alloy compositions examined in this work. As can be noted from this figure, the three partial pair correlation functions show the same overall aspect which reminds us of that of pure a-Si [18]. It shows that only the two first-neighbor shells are well defined (first-and second-nearest neighbors, respectively).…”

“…The starting point of our modeling of the structure of a-Si 1 − x Ge x alloy is the structural model recently developed in our research team for the amorphous silicon, called the nanoporous paracrystalline model [18]. It consists on a distribution of paracrystallites and nanopores in a continuous random matrix of amorphous silicon.…”

Small-Angle X-Ray Scattering of Amorphous Germanium: Numerical Modeling

“…for scattering vectors upper than 1 Å −1 . Some numerical simulations dealing with nanovoids in a-Si have been also reported in the literature [25][26][27][28][29][30][31], but only two, to the best of our knowledge, are interested in the small-angle scattering [25,26]. Biswas et al [25] were the first to demonstrate that CRN in which nanovoids are created accounts for the intense small-angle scattering, without altering the wide-angle scattering pattern.…”
