Superlubric polycrystalline graphene interfaces
Achieving ultra-low friction at macroscopic scales is highly desirable. In this work molecular dynamics simulations of graphitic contacts incorporating corrugated grain boundaries reveal an unusual non-monotonic variation of friction with normal load and temperature due to dynamic buckling effects.
