The high potentiality for graphene to be used in nanotechnology may lead to an augmentation of the band gap issue due to the fact that the single layer of graphene officially has a zero band gap. Therefore, the concept of bilayer and trilayer is introduced to achieve a tunable band gap by applying an external electrical field. Considering that there is a limit to increasing the band gap by using the external electrical field, this paper presents a novel method that will increase the band gap based on Hummer's fabrication method. The simulation results show a significant outcome in the band gap tuning. The tests in this paper were simulated in a MATLAB environment.
