1. A carbon nanotube array, comprising:

  • a substrate, wherein there is no catalyst immobilized on the substrate; and

    carbon nanotubes directly grown on the substrate without an intervening oxide layer between the substrate and a catalyst;

    wherein the carbon nanotubes are arranged as a vertically aligned carbon nanotube array on the substrate, andwherein the carbon nanotubes are covalently bonded to the substrate by a plurality of direct nanotube carbon-substrate covalent bonds.
