▎ 摘  要

NOVELTY - Forming graphene oxide-reduced graphene oxide junction, comprises: depositing a layer of graphene oxide; selectively exposing a region of the deposited graphene oxide layer to electromagnetic radiation to form a region of reduced graphene oxide adjacent to a neighboring region of unexposed graphene oxide, where the graphene oxide and adjacent reduced graphene oxide regions form a junction between them to produce a graphene oxide-reduced graphene oxide junction layer; and repeating deposition and exposure steps for at least one further respective layer of graphene oxide. USE - The method is useful for forming a graphene oxide-reduced graphene oxide junction (claimed) which is useful in proton batteries, electronic device, portable electronic device, portable telecommunications device, a mobile phone, personal digital assistant, a tablet, laptop computer, a desktop computer, a smartphone, a smartwatch, and proton battery. ADVANTAGE - The method provides the battery that exhibits increased electrical storage density. DETAILED DESCRIPTION - Forming a graphene oxide-reduced graphene oxide junction, comprises: depositing a layer of graphene oxide; selectively exposing a region of the deposited graphene oxide layer to electromagnetic radiation to form a region of reduced graphene oxide adjacent to a neighboring region of unexposed graphene oxide, where the graphene oxide and adjacent reduced graphene oxide regions form a junction between them to produce a graphene oxide-reduced graphene oxide junction layer; and repeating the deposition and exposure steps for at least one further respective layer of graphene oxide, over an underlying graphene oxide reduced graphene oxide junction layer, to produce an apparatus in which the respective junctions of the graphene oxide-reduced graphene oxide layers, when considered together, extend in the third dimension. INDEPENDENT CLAIMS are also included for: (1) apparatus comprising many overlying graphene oxide-reduced graphene oxide junction layers, where each graphene oxide-reduced graphene oxide junction layer comprises region of reduced graphene oxide adjacent to a neighboring region of graphene oxide, and the graphene oxide-reduced graphene oxide junction layers overlie one another such that the respective junctions of the layers, when considered together, extend in the third dimension; and (2) computer program comprising computer code configured to perform the method.
