It is widely known that graphene, monolayer graphite sheet, has unique physical properties such as extremely high mobility of carriers and quantized transport phenomena. Graphene has been synthesized mainly through a lab-based primitive method, and deposition method on large area is explored. We examined precipitation of graphene from a solid state metal and found thatamorphous graphite was precipitated through crystalline metal thin film.

众所周知，石墨烯，单层石墨片，具有独特的物理性质，如极高的载流子迁移率和量子化输运现象。石墨烯的合成主要采用实验室的原始方法，并探索了大面积沉积的方法。我们研究了石墨烯从固态金属中的沉淀，发现无定形石墨通过结晶金属薄膜沉淀。
