Nanoscale functionalized graphenes are fabricated by atomic force microscopy lithography with the desired coverage of a selective functional group using the simple method of the electrical control, and their recovery through moderate thermal treatments. Surprisingly, our controlled coverage of functional groups can reach 94.9% for oxygen and 49.0% for hydrogen, well beyond the coverage achieved by conventional methods.
