L-shaped and U-shaped Al2O3 nanowires were synthesized using a vapor phase deposition method. The as-grown nanowires are single crystalline and structurally uniform at the junction of the branches. Detailed TEM analysis revealed that the growth direction of the nanowires is parallel to the a- or b-axis directions, and switched growth from one direction to another forms the rectangular morphology of the peculiar L-shaped or U-shaped nanowires. Possible growth mechanism of the Al2O3 nanowires was explained. Our results can provide evidence to understand the growth mechanism of the complicated nanostructure.
