Two-Dimensional One-Atom-Thick Gold Grown on Defect-Engineered Graphene

Two-Dimensional One-Atom-Thick Gold Grown on Defect-Engineered Graphene

In this work, a general route to creating two-dimensional, one-atom-thick metal layers, metallene, on functionalized graphene is proposed. To explore its viability, low-energy ion irradiation is performed to introduce vacancies into initially pristine graphene, followed by ultralow-energy gold irrad...
