▎ 摘　　要

NOVELTY - Reducing resistivity in graphene layer comprises forming a single-layer graphene chromium chloride heterostructure in a graphene layer. USE - The method involves forming a single layer graphene CrOCl heterostructure, where the single layer graphene heterostructure is obtained by manually stacking hexagonal boron nitride, single layer graphene, and CrOCl. ADVANTAGE - The method has simple technique, using the novel effect of interlayer coupling which can simply obtain single layer of graphene-high conductivity, to develop ultra-thin light weight in the future, low resistance touch screen provides more excellent material selection. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the preparation of a single-layer graphene heterostructure. (Drawing includes non-English language text).
