DOI: 10.1007/s11249-019-1190-7
Abstract: Graphene has excellent lubricity because of its layer-stacking structure. However, after most fabricating processes, steps appear on the surface of graphene and can significantly affect its lubrication performance. Experimental studies often scratch the tip of… read more here.

DOI: 10.1103/physrevb.102.235412
Abstract: The passage of an electric current in a material can cause a biased mass transport at its surface. This migration phenomenon is intimately related to the microscopic details of atomic processes of diffusion and attachment/detachment… read more here.
