  abstract = {A recently developed molecular-dynamics simulation method for the growth of fully dense nanocrystalline materials by crystallization from the melt was used together with the Stillinger-Weber three-body potential to synthesize nanocrystalline silicon with a grain size up to 75 Angstrom. The structures of the highly-constrained grain boundaries ({GBs}), triple lines and point grain junctions were found to be highly disordered and similar to the structure of amorphous silicon. These and our earlier results for fcc metals suggest that a nanocrystalline microstructure may be viewed as a two-phase system, namely an ordered crystalline phase in the grain interiors connected by an amorphous, intergranular, glue-like phase. The analysis of the structures of bicrystalline {GBs} in the same materials reveals the presence of an amorphous intergranular equilibrium phase only in the high-energy but not the low-energy {GBs}, suggesting that only high-energy boundaries are present in nanocrystalline microstructures.
