Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
I doubt it. You must consider the geometry of the structures, the insulation and the conduction paths. There will be a problem with contact bonding between the carbon nanotube and the CCTO material. The fundamental problem is that the carbon nanotube has a huge surface area of carbon, not of CCTO. I think it much more probable that a conductive metal substrate will be used.
