We report the thickness dependence of intrinsic friction in few-layer graphenes, adopting molecular dynamics simulations. The friction force drops dramatically with decreasing number of layers and finally approaches zero with two or three layers. The results, which are robust over a wide range of temperature, shear velocity, and pressure are quantitatively explained by a theoretical model with regard to lateral stiffness, slip length, and maximum lateral force, which could provide a new… Expand

Using friction force microscopy, the nanoscale frictional characteristics of atomically thin sheets of graphene, molybdenum disulfide, niobium diselenide, and hexagonal boron nitride are compared to those of their bulk counterparts, suggesting that the trend arises from the thinner sheets’ increased susceptibility to out-of-plane elastic deformation.
