This method doubly takes advantage of residual oxygen present in the gas phase. First, by slightly oxidizing the copper surface, we induce grain boundary pinning in copper and, in consequence, the freezing of the thermal recrystallization process. Subsequent reduction of copper under hydrogen suddenly unlocks the delayed reconstruction, favoring the growth of centimeter-sized copper (111) grains through the mechanism of abnormal grain growth. Second, the oxidation of the copper surface also drastically reduces the nucleation density of graphene. This oxidation/reduction sequence leads to the synthesis of aligned millimeter-sized monolayer graphene domains in epitaxial registry with copper (111). The as-grown graphene flakes are demonstrated to be both single-crystalline and of high quality. 000057878 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2013-46159-C3-3-P$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 642742-Enabling Excellence$$9info:eu-repo/grantAgreement/EC/H2020/642742/EU/Graphene-based nanomaterials for touchscreen technologies: Comprehension, Commerce and Communication/Enabling Excellence$$9info:eu-repo/grantAgreement/EC/FP7/604391/EU/Graphene-Based Revolutions in ICT And Beyond/GRAPHENE$$9info:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2 000057878 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000057878 590__ $$a7.367$$b2016 000057878 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b23 / 275 = 0.084$$c2016$$dQ1$$eT1 000057878 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b13 / 87 = 0.149$$c2016$$dQ1$$eT1 000057878 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b21 / 166 = 0.127$$c2016$$dQ1$$eT1 000057878 591__ $$aPHYSICS, APPLIED$$b13 / 147 = 0.088$$c2016$$dQ1$$eT1 000057878 592__ $$a2.789$$b2016 000057878 593__ $$aNanoscience and Nanotechnology$$c2016$$dQ1 000057878 593__ $$aMaterials Science (miscellaneous)$$c2016$$dQ1 000057878 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000057878 700__ $$aTang, X. 000057878 700__ $$aJoucken, F. 000057878 700__ $$0(orcid)0000-0001-6152-6784$$aLajaunie, L. 000057878 700__ $$0(orcid)0000-0002-2071-9093$$aArenal, R.$$uUniversidad de Zaragoza 000057878 700__ $$aDubois, E. 000057878 700__ $$aHackens, B. 000057878 700__ $$aHenrard, L. 000057878 700__ $$aColomer, J.F. 000057878 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
