✦ Synopsis

Intercalation

of Ni atoms under a two-dimensional graphene film (ZDGF) on ( 111) Ir was studied in ultra high vacuum using high-resolution Auger spectroscopy.

Ni atoms were shown to be intercalated effectively at 900 to 1500 K, and a polylayer nickel film was shown to grow under the 2DGF. A relationship between a proportion n of Ni atoms intercalated under 2DGF and temperature, was determined and it was shown that ti decreases from -30% at 900 K to ~3% at 1500 K.
