Reducing graphene oxide using hydroiodic acid fumes and low temperature annealing for enhanced electrical conductivity

Abstract

In this work, a novel hybrid technique for reduction of graphene oxide is explored. The hybrid technique involves chemical reduction of graphene oxide coated over oxidized silicon substrate, by minimal exposure to HI acid fumes followed by low temperature thermal annealing under vacuum environment. Observations have shown improved conductivity as compared to other hybrid techniques and low temperature thermal annealing technique.
