Investigation of bandgap alteration in graphene oxide with different reduction routes

In the present investigation we report a comparative study of Graphene Oxide (GO) in regard to its bandgap variations arising due to different reduction methods such as thermal reduction (Heating), electrical reduction (Voltage Application) and chemical reduction (Hydrazine hydrate). This study reveals that among the GO three reduction method studied the voltage application is the most efficient one. It is found that band gap increases with...
