Abstract: Disclosed is AA′ graphite with a new stacking feature of graphene, and a fabrication method thereof. Graphene is stacked in the sequence of AA′ where alternate graphene layers exhibiting the AA′ stacking are translated by a half hexagon (1.23 Å). AA′ graphite has an interplanar spacing of about 3.44 Å larger than that of the conventional AB stacked graphite (3.35 Å) that has been known as the only crystal of pure graphite. This may allow the AA′ stacked graphite to have unique physical and chemical characteristics.

Abstract: The present disclosure relates to a method of growing a graphene nanopowder having a size of 10 nm or less into a graphene sheet having a seed size or more by using a graphene nanopowder as a seed. Further, in the present disclosure, a graphite sheet in which 2 to 20 layers of the graphene sheet are laminated may be prepared. The carbon sheet (that is, graphene and graphite sheets) may be prepared by preparing a graphene nanopowder (randomly distributed) on a substrate, and then subjecting the substrate to CVD treatment using a gas including a hydrocarbon gas in a chemical deposition apparatus.
