Nano World: Nanotubes arrayed on sapphire

Abstract:
Charles Q. Choi: Crystalline sapphire could help steer carbon nanotubes into orderly rows to create transistors and flexible electronics with, experts told UPI's Nano World. Chongwu Zhou at University of Southern California in Los Angeles and his team investigated if the surfaces nanotubes are grown on could automatically guide them. He and his colleagues found that sapphire could orient nanotubes into arrays. Sapphire crystals are much like hexagonal towers in shape, and most vertical cuts of sapphire presents its aluminum and oxygen atoms in arrangements that promote aligned growth.
