▎ 摘 要
NOVELTY - Method of designing defect-type graphene composite structure involves selected closing one end of armchair type C(6.6) single-walled nanotube, selecting a zero-dimensional nano graphene sheet as raw material, and then removing central portion of the zero-dimensional nano graphene sheet and forming defect. USE - Method of designing defect-type graphene composite structure (claimed). ADVANTAGE - The method efficiently and economically provides defect-type graphene composite structure having high field-emission properties.
