Determination of the electronic transport in type separated carbon nanotubes thin films doped with gold nanocrystals

Abstract We report a systematic theoretical and experimental investigation on the electronic transport evolution in metallic and semiconducting carbon nanotubes thin films enriched by gold nanocrystals. We used an ultra-clean production method of both types of single-walled carbon nanotube thin film...
