US Patent 7465494 - On insulator CNT array

This patent from Boston College teaches enhancing the field emission properties of carbon nanotube films via density control of the nanotube arrays formed on an intermediary non-metallic (e.g. SiO2) layer. Claim 1 reads:

1. A carbon nanotube material comprising an array of substantially linear carbon nanotubes with pre-determined densities that are attached to a catalyst substrate material including a metallic conductive layer deposited on a non-metallic material and a plurality of catalytic transition metal microparticles deposited upon the metallic conductive layer, wherein individual carbon nanotubes are aligned with respect to one another within said array.
