Graphene has gathered expectations as a new material that is perfect for electric devices. There was one problem. Graphene has no band gap which can control electric flow. Professor Cho Kil-won’s team (CE) composed graphene into a bernal-stacked multilayer, giving it a band gap to solve the problem. This was possible using a catalyst made by attaching a thin film of nickel onto the copper circuit board, controlling the number of layers. Prof. Cho said, “Band gap controlling is a source technology related to commercialization, and is expecting it to make great contributions in developing flexible mechanical devices.” This achievement is introduced in the academic journal Advanced Materials.
