<P>PROBLEM TO BE SOLVED: To produce high-quality graphene inexpensively and more easily into a large area. <P>SOLUTION: After dissolving carbon into a metal layer 102 by heating, the heating temperature is lowered, and carbon dissolved on the surface of the metal layer 102 is deposited, to thereby form graphene 104. For example, after dissolving carbon on a metal layer 102 comprising nickel by keeping the state at 900°C for 30 minutes, the temperature is lowered to a room temperature at the rate of 20°C per minute, to thereby deposit graphene 104 on the metal layer 102. <P>COPYRIGHT: (C)2013,JPO&INPIT |
