Graphene-based transparent conducting films were prepared using the following method.
A chemically-reduced graphene dispersion was synthesized and graphene films were prepared from it by transfer printing, followed by thermal treatment. The resulting graphene films possessed an excellent electrical conductivity with a high transparency. A sheet resistance lower than $2 KX/sq and a transparency well over 80% were achieved at a typical wavelength of 550 nm. These properties are considered quite sufficient for many applications, such as transparent conductor films for touch panels.

A predominantly semiconducting single-walled carbon nanotube-based thin conductive film was fabricated on a flexible poly(ethylene terephthalate) substrate. The structural features of the nanotubes and careful experimental scrutinization consistently yielded the films with very low surface resistanc

Silver (Ag) intermediate transparent and conducting TiON/Ag/TiON (TAgT) films were deposited by RF and DC magnetron sputtering on glass substrates. Changes in the optoelectrical properties of the films were investigated as a function of Ag thickness. The thickness of the Ag film varied from 5 to 20
