Caption

Transmission electron microscope images observed from the reduced graphene oxide films prepared by ethanol treatment at (a) 900ºC and (b) 1100ºC. For the high temperature treatment, the periodic bright spots are observed in the reduced graphene oxide films. This means that the crystallinity of the reduced graphene oxide is efficiently improved by high temperature treatment in ethanol environment.
