Characterization of transparent conducting carbon nanotube thin films prepared via different methods

The fabrication and characterization of transparent conductors based on single walled carbon nanotube (SWCNT) thin films were carried out in controlled environment and its performance compared. Here, we demonstrate the fabrication of thin, transparent, optically homogeneous, electrically conducting...
