WebSecondly, concentrated stress will generate at Gr/Cu interface considering their incoherent nature. Although graphene-lubrication effect shall reduce the stress concentration of Gr/Cu interface, however, such reduction, to our understanding, cannot last until the end of deformation process. Webhas been published that addressed the issues of incoherent interfaces in nanoscale metallic multilayers. Hoagland and co-workers have studied incoherent Cu–Nb interface [7,20]. That work was focused on the interaction of single, artiﬁcially introduced dislocations with the interface under essentially two-dimensional modeling conditions.
