### Toward near-bulk resistivity of Cu for next-generation

· Our findings suggest that near-bulk resistivity can be achieved in nanoscale Cu in the ideal case by the encapsulation of Cu with graphene layers. We have also demonstrated that the graphene coating greatly improves the stability of the conductivity of Cu thin films during bending by providing conduction channels in cracked regions.
