Growth, intercalation, doping, and local modification of graphene on the Ni(111) surface

The essence of the method used to form a graphene monolayer is the accumulation of carbon atoms under the nickel surface at room temperature and the subsequent carbon segregation on the nickel surface during heating. At each stage of the process, complete control of the reaction of graphene synthesis is possible by changing the temperature, heating time, and dose of the adsorbate (propylene). As a result, it is possible to create a single-domain (single-crystal) monolayer of graphene of a large area (5x5 mm or more), which upon subsequent intercalation with gold shows an ideal dispersion at  K point of the Brillouin zone. Graphene synthesis in this way allows to study the features of graphene growth at the atomic level, change the atomic composition of graphene (doping), intercalate it, and locally modify using a scanning tunneling microscope.
