Intercalation of platinum into a graphene film formed on molybdenum carbide Mo$_{2}$C

It has been shown that platinum atoms evaporation on graphene covering molybdenum carbide Mo$_{2}$C at $T$ = 1000 K causes platinum intercalation into the graphene. In such a case, a continuous multilayer platinum film grows under the graphene, which makes it possible to distinguish graphene-related components in the complex Auger spectrum of carbon.
