Intercalation of C60 Fullerene Molecules under Single-Layer Graphene on Molybdenum Carbide

Resumo

It is shown that heating of a fullerite film several monomolecular layers thick deposited onto single-layer graphene formed on a substrate of molybdenum carbide Mo₂C at T = 700–800 K leads to the intercalation of C₆₀ molecules under the graphene layer. The direct deposition of C₆₀ molecules at T = 650 K also leads to the intercalation of C₆₀ molecules under graphene; the maximal amount of fullerene accumulated under graphene is one single layer.
