Unexpected functions of oxygen in a chemical vapor deposition atmosphere to regulate graphene growth modes.
Herein, by controlling the oxygen concentration in a graphene growth process, we reveal that the ppm grade of oxygen in the graphene growth atmosphere can tune the graphene growth modes of multilayer growth and graphene etching fragments.
