▎ 摘　　要

NOVELTY - A substrate is patterned, to form elements (104-1-104-2,104-N) on the substrate. Each element is separated from an adjacent element on the substrate by a corresponding trench in trenches (106-1,106-2) on the substrate. Each element has a corresponding top surface. The top surface of each element is separated from an adjacent trench surface by a side wall of the element. A graphene initiating layer is segmentedly deposited on the top surface of each element. Graphene is generated using the graphene initiating layer, to form graphite-based structure. USE - Method for forming graphite-based structure e.g. graphene quantum dots, graphene nanoribbons, graphene nanonetworks, graphene plasmonics and graphene super-lattices used for electronic devices, composite materials and energy generation and storage. ADVANTAGE - The method enables formation of graphite-based structure with controlled device fabrication, excellent spatial resolution and packing density of segmented graphene layers. DETAILED DESCRIPTION - A substrate is patterned, to form elements on the substrate. Each element is separated from an adjacent element on the substrate by a corresponding trench in trenches on the substrate. Each element has a corresponding top surface. Each trench has a trench surface, and separates a pair of adjacent elements in the elements. The top surface of each element is separated from an adjacent trench surface by a side wall of the element. Top surface of a primary element has a primary elevation. The trench surface of a primary trench has a secondary elevation. The primary elevation is other than the secondary elevation. A primary orthogonal projection of the top surface of the primary element and a secondary orthogonal projection of the trench surface of the primary trench on a common plane are contiguous or overlapping. A graphene initiating layer is segmentedly deposited on the top surface of each element. Graphene is generated using the graphene initiating layer, to form graphite-based structure. An INDEPENDENT CLAIM is included for graphite-based structure. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of graphene device topography.
