title: The structure of graphene/nickel interfaces within nickel-encapsulating carbon nanocapsules studied by high-resolution transmission electron microscopy.
abstract: Nickel (Ni)-encapsulating carbon nanocapsules (CNCs) were synthesized by vacuum deposition. The graphene/Ni interfaces within the CNCs were observed by high-resolution transmission electron microscopy. From lattice imaging, the orientational relationship and atomic configuration at the interfaces were investigated. It was found that the interlayer spacing at the (0001)graphene/(001)Ni interfaces was 0.21 +/- 0.05 nm. The interfaces within Ni3C-encapsulating CNCs, synthesized by the same method, were also examined.
