Large area graphene layer synthesis
The large area graphene layer is synthesized by a conventional metal melting method (MMM). And we use the mechanism of diamond synthesis in liquid phase and produced graphene of about 5×7cm2. This promising process appears scalable for making device-sized graphene in the near future. This paper also presented many intriguing aspects related to the growth of large graphene. We also proposed a new hypothesis of graphene formation by the recrystallization of graphite in molten iron group alloys.
