▎ 摘　　要

NOVELTY - A graphite-based device comprises substrate (102) comprising zones (102-1,102-2,102-3,102-4); and graphene stacks (104-1,104-2,104-3,104-4). The first graphene stack is formed in first zone, and comprises first non-planar graphene layer having first bending angle or first curvature. The second graphene stack is formed in second zone and comprises second non-planar graphene layer having second bending angle or second curvature. USE - As graphite-based device (claimed) (e.g. graphene quantum dots, graphene nanoribbons (GNRs), graphene nanonetworks, graphene plasmonics and graphene super-lattices) useful in electronic devices; and also useful in many applications, including self-centering devices, such as conic devices for interacting with photons in resonance or variable wavelength ranges, solar cells for tracking solar photons, reflection or concentration devices for redirecting or concentrating photons to a target region, and antenna arrays for absorbing or emitting photons in specific wavelength ranges. ADVANTAGE - The controllable, reliable and precise graphite-based device has large workable surface areas and high packing densities. The device has large workable surface areas that surpass the underlying physical surface areas, and consequently enhances functionalities; and also improves efficiency or other functionalities. The graphite-based device has a wide variety of configurations to achieve desired functionalities for various applications.
