Abstract
According to the present invention, oxidized and reduced regions of graphene can be accurately detected in a short time using a terahertz wave so as to measure the conductivity of graphene, and thus the time required to test the conductivity of graphene can be reduced. In addition, when an oxidized region exists in graphene, the oxidized region can be immediately reduced by irradiating an electromagnetic wave thereto so as to increase the conductivity of graphene and thus minimize the time required to restore graphene.
