Robust ultra-low-friction state of graphene via moiré superlattice confinement

Two-dimensional materials show remarkable lubrication properties, yet chemical modifications may hinder such capabilities. Here, the authors show that when graphene is aligned on a Ge(111) substrate, ultra-low friction can be preserved even after graphene fluorination or oxidation.
