Transition metal dichalcogenide heterostructures with layers of localized and itinerant electrons are candidates for heavy fermion lattices. The authors report delocalization of Mott electrons in a monolayer of 1T-TaS2 on a bulk metallic 2H-TaS2 substrate, indicating the formation of a coherent Kondo lattice.
