J. T. Han, K. Cho, and co‐workers demonstrate on page 8141 the controllable, strong, and stable doping of chemical‐vapor‐deposition (CVD)‐grown graphene with atomically thin and chemically versatile monolayer graphene oxide (GO) sheets. The doping effects of GO on the graphene can be controlled by varying the coverage of GO and its degree of functionality. The proposed doping method also almost maintains the intrinsic roughness (ca. 0.55 nm) and transparency (ca. 96.7 %) of the graphene, as well as its long‐term conductivity in air. Owing to these excellent properties, GO‐doped graphene is promising as electrode in optoelectronic devices.
