▎ 摘　　要

NOVELTY - The method involves dissociating graphite or graphene to expose fresh surface that is placed at atomic force microscope sample table. An end of graphite or graphene is grounded by a lead, and graphite or graphene surface is scanned by an atomic power microscope. Areas to be etched are selected, and graphite or graphene surface is approached by a needle tip of the atomic force microscope. Scanning range is set, and negative voltage is applied to the needle tip. The graphite or graphene is etched to form a groove to obtain a designed processing pattern. USE - Method for processing nanometer scale figure at graphite or surface of graphene for processing food ADVANTAGE - The method enables providing multi-needle tip effect and obtaining narrow etching grooves by etching. DESCRIPTION OF DRAWING(S) - The drawing shows a photographical representation illustrating nanometer scale figure at graphite or surface of graphene.
