Scholarcy highlights

  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • The synthesis of wafer-scale single crystal graphene remains a challenge toward the utilization of its intrinsic properties in electronics
  • The large-area chemical vapor deposition of graphene has yielded a polycrystalline material, where grain boundaries are detrimental to its electrical properties
  • Graphene arises from the crystallization of a supersaturated fraction of carbon-adatom species, and its nucleation density is the result of competition between the mobility of the carbon-adatom species and their desorption rate
  • The growth-limiting step was found to be the attachment of carbon-adatom species to the graphene edges, which was independent of the Cu crystalline orientation
