Mechanotunable monatomic metal structures at graphene edges.

摘要: Monatomic metal (e.g. silver) structures could form preferably at graphene edges. We explore their structural and electronic properties by performing density functional theory based first-principles calculations. The results show that cohesion between atoms, as well coupling atoms edges offer remarkable stability of the hybrid. find outstanding mechanical allow tunable monatomic straining structure. concept is extended to rings helices open ends carbon nanotubes twisted ribbons. These findings demonstrate role an efficient one-dimensional template for low-dimensional are mechanotunable.
