Summary: | Reduced graphene oxide (rGO) has been produced using an ammonia (NH3) plasma reduction method. Simultaneous nitrogen doping during the reduction process enabled a rapid and low-temperature restoration of the electrical properties of the rGO. The chemical, structural, and electrical properties of the rGO films were analyzed using x-ray photoelectron spectroscopy, Raman spectroscopy, atomic force microscopy, and conductivity measurements. The oxygen functional groups were efficiently removed, and simultaneous nitrogen doping (6%) was carried out. In addition, the surface of the rGO film was flattened. Consequently, the rGO films exhibited electrical properties comparable to those prepared via other reduction methods.
