  ABSTRACT: We investigated the effect of dissolved hydrogen on the microstructure evolution of nanocrystalline silicon. Through molecular dynamics simulations we characterize the local and overall structural features of several hydrogenated samples by the quantitative calculation of their crystallinity. We prove that hydrogen incorporation is detrimental for the recrystallization and accumulates at grain boundaries, thus increasing their effective area. We further observe the formation of silicon hydrogen complexes at very high hydrogen concentration. Comment: submitted for publication
