The rocking curve analysis performed, based on the dynamical diffraction theory, shows that the spacing between the graphene layer and a substrate of Cu(111) and that between graphene and a Co(0001) substrate are 3.34 A and 2.06 A, respectively. The former is close to the interlayer spacing in graphite, suggesting a weak interaction with the substrate material, whereas the latter value experimentally verifies that, in the case of graphene on Co(0001), there is a strong interaction with the substrate.}, pages = {1--4}, title = {Spacing between graphene and metal substrates studied with total-reflection high-energy positron diffraction}, volume = {103}, year = {2016} }
