Title:
METHOD FOR THE LOCALIZED GROWTH OF NANOTHREADS OR NANOTUBES
Document Type and Number:
WIPO Patent Application WO2005015596
Kind Code:
A3
Abstract:
The invention relates to a method for the localized growth of nanothreads or nanotubes, characterized in that said method comprises the following steps: creation of elementary conductive surfaces on the surface of an insulating substrate; creation of at least one nanoporous structured layer on the surface of the insulating layer or insulating substrate; growth of nanothreads inside part of at least the nanopores of the porous layer opposite at least one part of the elementary conductive surfaces. Advantageously, creation of the nanoporous structured layer on the surface of the insulating layer or insulating substrate can include deposition of a precursor layer of a porous structured layer that includes nanopores; ionic bombardment of the precursor layer in order to obtain the porous structure layer. The invention can be used for a field emission substrate, for flat screens.
