Abstract

Transparent conductors based on few-layer graphene (FLG) intercalated with ferric chloride (FeCl3) have an outstandingly low sheet resistance and high optical transparency. FeCl3-FLGs outperform the current limit of transparent conductors such as indium tin oxide, carbon-nanotube films, and doped graphene materials. This makes FeCl3-FLG materials the best transparent conductor for optoelectronic devices.
