Graphene synthesis chamber and method of synthesizing graphene by using the same

Abstract

A graphene synthesis chamber includes: a chamber case in which a substrate including a metal thin film is placed; a gas supply unit which supplies at least one gas comprising a carbon gas into an inner space of the chamber case; a main heating unit which emits at least one light to the inner space to heat the substrate; and at least one auxiliary heating unit which absorbs the at least one light and emits radiant heat toward the substrate.

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS[0001]This application claims priority from Korean Patent Application No. 10-2011-0023829, filed on Mar. 17, 2011, and Korean Patent Application No. 10-2011-0069490, filed on Jul. 13, 2011, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference.BACKGROUND[0002]1. Field[0003]Apparatuses and method consistent with exemplary embodiments relate to a graphene synthesis chamber and synthesizing graphene by using the same.[0004]2. Description of the Related Art[0005]In general, graphite is a stack of two-dimensional (2D) graphene sheets having a plate shape in which carbon atoms are connected to one another in a hexagonal shape. After examining graphene peeled off from graphite, it has been found recently that graphene has very useful properties that are different from those of existing materials.[0006]One remarkable property of graphene is that when electrons move therein, th...

AI Technical Summary

Benefits of technology

[0009]One or more exemplary embodiments provide a graphene synthesis chamber allowing easy thermal control.

Problems solved by technology

Although graphene has very useful properties as described above, since it takes a relatively long time to set a high-temperature / high-vacuum environment in order to synthesize graphene, it is difficult to mass produce large graphene sheets at low costs.
