▎ 摘 要
NOVELTY - Transferring a graphene film, involves: (A) providing a carrier, where the carrier have first and second surfaces, and a first graphene film is formed on the first surface of the carrier; (B) disposing a patterned protection layer on the second surface of the carrier; (C) patterning the carrier to expose the first graphene film, where the pattern of the carrier corresponds to the patterned protection layer; (D) disposing the patterned carrier with the first graphene film on a target substrate; and (E) removing the patterned carrier to transfer the graphene film onto the target substrate. USE - The method is useful for transferring a graphene film (claimed), or other carbon films including diamond films, diamond-like films, and other composite carbon films with or without metals of relevant dopants or additives. ADVANTAGE - The method is capable of effectively transferring a graphene film with low chemical and mechanical damage to improve the quality of graphene film transfer. DETAILED DESCRIPTION - Transferring a graphene film, involves: either (A) providing a carrier, where the carrier have first and second surfaces, and a first graphene film is formed on the first surface of the carrier, (B) disposing a patterned protection layer on the second surface of the carrier, (C) patterning the carrier to expose the first graphene film, where the pattern of the carrier corresponds to the patterned protection layer, (D) disposing the patterned carrier with the first graphene film on a target substrate, and (E) removing the patterned carrier to transfer the graphene film onto the target substrate; or (A1) the step (A) as above per se, (B1) disposing the carrier in a carrier-removing solution to remove the carrier, and the first graphene film suspends on the carrier-removing solution, (C1) replacing the carrier-removing solution with a suspension solution, where the first graphene film suspends on the suspension solution, (D1) separating the first graphene film from the suspension solution, and (E1) transferring the first graphene film onto a target substrate.
