Excess resistivity in graphene superlattices caused by umklapp electron–electron scatteringExcess resistivity in graphene superlattices caused by umklapp electron–electron scattering, Published online: 15 October 2018; doi:10.1038/s41567-018-0278-6An increase in electrical resistance caused by the fundamental process of electrons scattering off of each other (umklapp scattering) is observed in graphene superlattice devices. This will limit the electrical properties of such devices.
