Improvement of SWCNT transparent conductive films via transition metal doping

Abstract

To realize transparent conductive films based on single-walled carbon nanotubes (SWCNTs), we applied a spray coating process with transition metal doping to SWCNT networks. Schottky contacts between metallic and semiconducting SWCNTs changed to Ohmic contacts due to the reduction of metals on the SWCNT surfaces via direct conversion from solution.
