The growth behaviour of carbon layers formed on a Pt(111) surface has been investigated by means of scanning tunnelling microscopy. A carbon layer with a (√19 × √19)R23.4° structure was grown by benzene exposure of 3 L at 1000 K. After exposure of >10 L, graphene islands with hexagonal shapes appeared in the surface terraces. The graphene islands grew beyond step edges, and their growth often caused bunching of the step edges by Pt atom migration.
