ImpactModerate impact

Many contributors recognize that the research could influence future developments in graphene device fabrication and material engineering, indicating a moderate perceived impact.

Abstract in brief

Epitaxial graphene grown on Cu111 foils is free of wrinkles and experiences biaxial compressive strain, which varies depending on the orientation and adhesion with the substrate.
The strain relaxation occurs through the loss of local adhesion and the formation of wrinkles, with a larger frictional force between the graphene and Cu111 making wrinkle formation more difficult.
Chemically, epitaxial graphene on Cu111 shows increased reactivity compared to graphene on polycrystalline copper, likely because the higher compressive strain reduces formation energy or the energy gap, enhancing chemical reactions.
