▎ 摘　　要

NOVELTY - Organic electronic device structure comprises a graphene layer on which organic molecules (with/without dopants) are deposited to form an organic layer on top of the graphene layer, where after some distance in the direction perpendicular to the graphene layer when the influence (of the potential) exerted by the graphene layer begins to wane, another graphene layer is deposited onto the organic layer, and the structure can be used (in any order) in conjunction with another such structure, or partial/complete layer/layers of any material/aggregate of materials. USE - Used as an organic electronic device structure. ADVANTAGE - The organic electronic device structure: is obtained in the method which utilizes annealing step that recovers some degradation or all or some of its lost functionality (claimed), and thus there is an increase in the strength, life and flexibility of the structure, when compared to the structure in which flakes of graphene are randomly distributed in an organic layer; and exhibits increased reproducibility and uniformity of performance in the industrial production area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene layer may be deposited at the interface of two different layers in the organic electronic device structure, where the graphene layer is deposited on an organic layer of one material, and a second organic layer of second material is deposited on top of the graphene layer; and (2) preparation of graphene sheet/sheets that makes/make up the graphene layer, comprising: using a substrate that is cylinder or cylinder-like in shape; un-patterning the surface of the roller substrate, or pre-patterning the surface to produce patterned graphene sheet/sheets and/or the surface having protrusions to produce patterned graphene sheet/sheets; and rotating the roller substrate (when the roller-substrate replaces the conventional flat substrates in a chemical vapor deposition technique), so that only a part of the substrate is exposed to the incoming chemical vapor at any one time, and after one rotation, at least one monolayer of continuous/non-continuous graphene sheet is formed, where the process of transfer of graphene sheet/sheets includes directly rolling the roller-substrate onto the desired location and applying an adhesive at the desired location to help the graphene sheet adhere, and the roller-substrate surface-material includes nickel and other transition metals.
