Abstract

Current application was found to enhance the crystallinity of multilayer graphene during CVD using a Ni catalyst layer. However, the reduction of surface roughness has been the issue. The effect of current to the Ni catalyst layer was investigated, and it was found that the current promotes the growth of Ni (111) grains, leading to the enhanced compressive stress. After reaching the stress limit, the Ni microstructure changed again and the stress was relaxed. Such microstructure changes in the Ni film correlated with the surface roughness.
