▎ 摘　　要

NOVELTY - A graphene manufacturing method involves preparing basic graphene i.e. pristine graphene, and accelerating argon ions. A basic graphene ion in the basic graphene is irradiated and accelerated. USE - Method for manufacturing graphene. ADVANTAGE - The basic graphene ion in the basic graphene is irradiated and accelerated, thus effectively controlling work function of the grahene. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for controlling working function of graphene. '(Drawing includes non-English language text)'
