    Abstract

    Bicrystal AIN zigzag nanowires have been synthesized by directly nitriding aluminum powders using Fe-(NO3)(3) as a catalyst. The structural characterizations reveal that there are three types of grain boundaries between the two single crystals. The lattice mismatches along these boundaries cause asymmetrical residual stresses, which tilt these boundaries to different directions, leading to the formation of a zigzag morphology. The transitions between these boundaries offset these lattice mismatch stresses and stabilize the structure.
