▎ 摘　　要

NOVELTY - Forming graphite-based device on substrate (102), involves creating graphene foundation layers on the substrate, where the graphene layers comprise at least one non-planar graphene foundation layer; and concurrently generating a graphene stack (104-1, 104-2) from the graphene foundation layers, where the graphene stack comprises graphene layers including a first non-planar graphene layer that is defined by a first feature that is (i) a first bending angle, (ii) a first curvature, (iii) a first characteristic dimension, (iv) a first graphene orientation, and/or (v) a first graphene type. USE - For forming a graphite-based device on a substrate (claimed) which is used in self-centering devices such as conic devices that can interact with photons in resonance or variable wavelength ranges, solar cells that can track solar photons, reflection or concentration devices that can redirect or concentrate photons to a target region, and antenna arrays that can absorb or emit photons in specific wavelength ranges. ADVANTAGE - The method provides controllable, reliable and precise graphite-based structures without patterning the graphene layers, and with multiple or enhanced functionalities; and has ability to provide multiple functions in the same device allows for more versatile and efficient devices (such as solar devices), integration of broadband devices (EUV through IR), increased efficiency by the design of elements to capture maximum peak wavelength energy, generation of neighboring effects of different functionality of graphene (single and multiple layers), reduced resistivity by use of more sheets, band gap tune ability, work function definition, denser packing of device, shorter mean free paths, better capture of photons, cascade devices (sometimes called stair case devices) where photons or wavelengths are stripped from top to bottom, advantageous optical properties and electrical interactions (e.g. sensing and response to specific wavelength at each level). The graphite-based device achieves desired size, specified geometries, and characterized electronic/photonic properties. DETAILED DESCRIPTION - Forming a graphite-based device on a substrate (102), involves creating graphene foundation layers on the substrate, where the graphene layers comprise at least one non-planar graphene foundation layer; and concurrently generating a graphene stack (104-1, 104-2) from the graphene foundation layers, where the graphene stack comprises graphene layers including a first non-planar graphene layer that is defined by a first feature that is (i) a first bending angle, (ii) a first curvature, (iii) a first characteristic dimension, (iv) a first graphene orientation, and/or (v) a first graphene type, and where the graphene stack comprises a first transition region that partitions at least a portion of the graphene stack into a first portion and a second portion, where the first portion of the graphene stack is defined by more graphene sheets than the second portion of the graphene stack and where at least one of the graphene layers in the graphene layers is common to the first portion and the second portion of the graphene stack.
