"Webthe resistance between HOPG and graphene scrolls is very low, and this can be explained by the scrolls and HOPG having atomically smooth lattices at the contact region. In addition to a smooth contact, both HOPG and the scrolls have similar work functions and therefore energy-level alignment can occur at the HOPG–scroll interface. " - Hopg work function
