▎ 摘　　要

NOVELTY - System and realizing band gap opening in graphene, comprises firstly, cleaning monolayer of graphene sheet grown in large area on copper foil and neatly cutting using scissor, stacking two graphene sheets together with copper foils, rolling the stacked graphene sheets with copper foil by roll mill for plastic deformation of graphene, subsequently, to break the symmetry in the bilayer graphene sheets, transferring plastic deformed graphene on the hexagonal boron nitride/substrates, and further, performing Raman spectroscopy and infrared spectroscopy on the samples for the confirmation of band gap opening in the graphene. USE - The system and the method are useful for: realizing band gap opening in graphene; and inducing band gap in bilayer graphene transferred on hexagonal boron nitride (all claimed). ADVANTAGE - The system and the method: are easy and cost effective; utilizes roll bonding process for severe plastic deformation, thus increasing hardness of the system; and provides induced band gap in bilayer graphene, thus exhibiting enhanced electrical and mechanical properties on a massive scale for commercial applications in electronic industry.
