The carbon's solubility into copper is amazingly small and as a consequence mainly surface diffusion and nucleation of carbon atoms are involved. For that reason and the growth kinetics, the graphene thickness is restricted to predominantly a monolayer. The large advantage would be that the graphene can be developed on https://www.facebook.com/permalink.php?story_fbid=pfbid0Zkff5axPy6uAtu7ed6jL7bBkwRNQEiAdoff9FT6dTCiHjS7GfgNMKvgNrf2mHVSvl&id=61562415773754&__cft__[0]=AZUI90kXm6CF6WoBAoZpB--pN0ExuRPIfNrUipwWeTq75wQFBs2jd06YYlMjt9ypC06o0VzAripYTDyjtQ27LDW2agoiG8cq9hmV7HjUa7VSDgwTmV1UXdtYQdRO6BbQJ9t_ngaTGgccCTSq9QJEAIFpXosT23jashvb28TDuSJZb3q2jvmVkoRA73NDeQQCtly1ns3YbwrOOXRH2-Vp8O-t&__tn__=%2CO%2CP-R
