How does your graphene grow? In situ X‐ray photoelectron spectroscopy and X‐ray diffraction measurements during chemical vapor deposition on Ni catalyst films show that graphene forms both isothermally and by precipitation on cooling (see picture). A coherent graphene growth model is devised and sub‐surface dissolved carbon is shown to play an important role.
