Carbon Nanotubes with a Triangular Cross-section, Fabricated Using Anodic Porous Alumina as the Template



The fabrication of carbon nanotubes (CNTs) with controlled cross-sectional shapes is reported for the first time. Anodic porous alumina with triangular openings is used as a template for the chemical vapor deposition synthesis of the CNTs with triangular cross-sections (see Figure). The CNTs can be applied to the fabrication of nanoscale devices that require modified electronic characteristics.
