Apparatus and method for synthesizing vertically aligned carbon nanotubes
Methods and devices to synthesize vertically aligned carbon nanotube (VACNT) arrays directly on a catalytic conductive substrate without addition of an external metallic catalyst layer and without any pretreatment to the substrate surface using a plasma enhanced chemical vapor deposition (PECVD) method are provided. A method comprises providing a catalytic conductive substrate, that has not been pretreated through a plasma enhanced chemical vapor deposition (PECVD) method or other methods, to a PECVD device, etching the catalytic conductive substrate to form catalytically active nano-features on the surface of the catalytic conductive substrate, and growing vertically aligned carbon nanotubes on the surface of the catalytic conductive substrate, without an external metallic catalyst layer, by providing a carbon source gas to the catalytic conductive substrate.
