摘要： The present invention relates to a method of producing graphene and/or graphene oxide. The method comprises providing a copper-based sheet coated on one side with a carbonaceous material; providing a bath comprising an aqueous solution comprising a salt of at least one ion selected from Li + , Na + , K + , Mg 2+ or Ca 2+ , in which bath a first electrode is arranged; feeding the copper-based sheet into the bath; applying a first voltage between the copper-based sheet and the first electrode; applying a second voltage, reversed as compared to the first voltage, between the copper-based sheet and the first electrode, such that graphene and/or graphene oxide is exfoliated from the carbonaceous material. The present inventio also relates to a system for producing graphene and/or graphene oxide. The present invention also relates to a graphene material formed as crystalline, self-supporting hexagonal flakes. The present invention also relates to a graphene material formed as crystalline, self-supporting flakes comprising dendrites.

摘要： A method for direct growth of multilayer graphene used as a core layer of a pellicle for extreme ultraviolet lithography is provided. In addition, a method for manufacturing the pellicle for extreme ultraviolet lithography by using the multilayer graphene direct growth method is provided. The multilayer graphene direct growth method includes forming few-layer graphene on a silicon nitride substrate, forming a metal catalyst layer on the few-layer graphene, forming an amorphous carbon layer on the metal catalyst layer, and directly growing multilayer graphene from the few-layer graphene used as a seed layer by interlayer exchange between the metal catalyst layer and the amorphous carbon layer through heat treatment.
