Journal ArticleDOI
Graphene Oxidation: Thickness-Dependent Etching and Strong Chemical Doping
Li Liu,Sunmin Ryu,Michelle R. Tomasik,Elena Stolyarova,Naeyoung Jung,Mark S. Hybertsen,Michael L. Steigerwald,Louis E. Brus,George W. Flynn +8 more
TL;DR: It is found that O 2 etching kinetics vary strongly with the number of graphene layers in the sample, and three-layer-thick samples show etching similar to bulk natural graphite.
Journal ArticleDOI
Atmospheric Oxygen Binding and Hole Doping in Deformed Graphene on a SiO2 Substrate
Sunmin Ryu,Li Liu,Stéphane Berciaud,Young-Jun Yu,Haitao Liu,Philip Kim,George W. Flynn,Louis E. Brus +7 more
TL;DR: It is proposed that oxygen molecular anions are stabilized by water solvation and electrostatic binding to the silicon dioxide surface and become stronger and more irreversible in the presence of moisture and over long periods of time.
Journal ArticleDOI
Observation of Graphene Bubbles and Effective Mass Transport under Graphene Films
Elena Stolyarova,Daniil Stolyarov,Kirill I. Bolotin,Sunmin Ryu,Li Liu,Kwang Taeg Rim,Martin Klima,Mark S. Hybertsen,Igor Pogorelsky,I. V. Pavlishin,Karl Kusche,James Hone,Philip Kim,Horst Stormer,Vitaly Yakimenko,George W. Flynn +15 more
TL;DR: In this article, the authors demonstrate the robustness of single layer graphene membranes, which are capable of containing mesoscopic volumes of gas and effective mass transport at the graphene/SiO2 interface.
Journal ArticleDOI
Graphene cover-promoted metal-catalyzed reactions
Yunxi Yao,Qiang Fu,Yu-Yang Zhang,Xuefei Weng,Huan Li,Mingshu Chen,Li Jin,Aiyi Dong,Rentao Mu,Peng Jiang,Li Liu,Hendrik Bluhm,Zhi Liu,Shengbai Zhang,Xinhe Bao +14 more
TL;DR: It is demonstrated here that CO adsorption and oxidation can occur on Pt surface covered by monolayer graphene, showing that the space between graphene overlayer and metal surface can act as a two-dimensional (2D) nanoreactor.
Journal ArticleDOI
Forming Aromatic Hemispheres on Transition‐Metal Surfaces
Kwang Taeg Rim,Mohamed Siaj,Shengxiong Xiao,Matthew Myers,Vincent D. Carpentier,Li Liu,Chaochin Su,Michael L. Steigerwald,Mark S. Hybertsen,Peter H. McBreen,George W. Flynn,Colin Nuckolls +11 more
TL;DR: The interaction of hexabenzocoronene (1, HBC), a large and multifunctional molecule, with a clean ruthenium surface is described and it is concluded that 1 bonds “face-on” to the Ru(0001) surface.
