We study the quantum corrections caused by electron-electron (e-e) interactions and localization to the conductivity in few-layer epitaxial graphene, in which the carriers responsible for transport are massive. Our results demonstrate that the diffusive model, which can generally provide good insights into the magnetotransport of two-dimensional systems in conventional semiconductor structures, is applicable to few-layer epitaxial graphene when the unique properties of graphene on the substrate such as intervalley scattering are taken into account. We suggest that magnetic-field-dependent e-e interactions and Kondo physics are required for obtaining a thorough understanding of magneto-transport in few-layer epitaxial graphene.
