Graphene growth on the textured copper surface

The effect of mechanical processing of copper foil on the single-layer graphene growth is studied. The deformation of the foil in the annealed and unannealed state is carried out by rolling between rollers with varying degrees of roughness. It is shown that the formed single-layer graphene coating on the foil deformed in the unannealed state has a larger number of defects, which is associated with the heterogeneity of the copper texture formed upon annealing. In the case of rolling the copper foil after the annealing stage, the quality of graphene coatings only slightly deteriorates in the deformed areas of foil.
