Graphene, renowned for its exceptional electronic and optical properties as a robust two-dimensional (2D) material, traditionally lacks electronic correlation effects. Proximity coupling offers a promising method to endow quantum materials with novel properties. In this study, we realized a 2D heterostructure by intercalating Sn into zero layer graphene on SiC(0001), allowing us to explore the coupling between a correlated 2D electron gas and a Dirac metal. This results in the stabilization of Sn- 3 superlattice structures at the interface, which reveal Mott-Hubbard bands, in qualitative agreement with both experimental observations and theoretical predictions.
