  • Title: Organic nanowire-templated fabrication of alumina nanotubes by atomic layer deposition.
    Author: Wang CC, Kei CC, Yu YW, Perng TP.
    Journal: Nano Lett; 2007 Jun; 7(6):1566-9. PubMed ID: 17518504.
    Abstract:
    Alumina nanotubes were fabricated by a template method. Tris-(8-hydroxyquinoline) gallium (GaQ3) organic nanowires were used as a soft template for coating with alumina using an atomic layer deposition technique. The deposition was conducted at 25 degrees C by using trimethylaluminum and distilled water as the precursors of Al2O3. Amorphous alumina nanotubes were obtained after removing the GaQ3 by dissolving in toluene or by heat treatment at 350 degrees C. The amorphous nanotubes could be crystallized by heating at 900 degrees C for 1 h in vacuum.
