Graphene-silica composite thin films as transparent conductors.
نویسندگان
چکیده
Transparent and electrically conductive composite silica films were fabricated on glass and hydrophilic SiOx/silicon substrates by incorporation of individual graphene oxide sheets into silica sols followed by spin-coating, chemical reduction, and thermal curing. The resulting films were characterized by SEM, AFM, TEM, low-angle X-ray reflectivity, XPS, UV-vis spectroscopy, and electrical conductivity measurements. The electrical conductivity of the films compared favorably to those of composite thin films of carbon nanotubes in silica.

متن کاملNovel Highly Conductive and Transparent Graphene-Based Conductors
Transparent conductors based on few-layer graphene (FLG) intercalated with ferric chloride (FeCl(3)) have an outstandingly low sheet resistance and high optical transparency. FeCl(3)-FLGs outperform the current limit of transparent conductors such as indium tin oxide, carbon-nanotube films, and doped graphene materials. This makes FeCl(3)-FLG materials the best transparent conductor for optoele...
متن کاملHybrid thin films of graphene nanowhiskers and amorphous carbon as transparent conductors.
A new form of hybrid carbon-based thin film was prepared via a pyridine chemical vapour deposition method. The as-obtained films consist of agglomerated flowerlike graphene nanowhiskers embedded in a uniform matrix of amorphous carbon. Schottky solar cells made from the hybrid films and n-type silicon show conversion efficiencies of approximately 1% under AM 1.5 illumination.
