  • Title: Grain boundary mapping in polycrystalline graphene.
    Author: Kim K, Lee Z, Regan W, Kisielowski C, Crommie MF, Zettl A.
    Journal: ACS Nano; 2011 Mar 22; 5(3):2142-6. PubMed ID: 21280616.
    Abstract:
    We report direct mapping of the grains and grain boundaries (GBs) of large-area monolayer polycrystalline graphene sheets, at large (several micrometer) and single-atom length scales. Global grain and GB mapping is performed using electron diffraction in scanning transmission electron microscopy (STEM) or using dark-field imaging in conventional TEM. Additionally, we employ aberration-corrected TEM to extract direct images of the local atomic arrangements of graphene GBs, which reveal the alternating pentagon-heptagon structure along high-angle GBs. Our findings provide a readily adaptable tool for graphene GB studies.
