GRAPHENE QUALITY EVALUATION DEVICE AND GRAPHENE QUALITY EVALUATION METHOD USING ELECTROMAGNETIC INDUCTION

摘要

A graphene quality evaluation device comprises: at least one electromagnet arranged to be adjacent to a graphene; a driving unit providing an electric signal having a changed size in the electromagnet to generate a magnetic field having changed intensity in the electromagnet; an induced voltage measuring unit measuring induced voltage induced in the graphene by the magnetic field generated in the electromagnet; and a quality evaluation unit evaluating graphene quality based on the induced voltage. Therefore, the graphene quality evaluation device can evaluate quality by quantifying a structural defect of the graphene.
