Abstract

Magnetic metals deposited on graphene hold the key to applications in spintronics.Here,we present the results of Fe islands grown on graphene/SiC(0001)by molecular beam epitaxy,which are investigated by scanning tunneling microscopy.The two types of islands distinguished by flat or round tops are revealed,indicating bimodal growth of Fe.The atomic structures on the top surfaces of flat islands are also clearly resolved.Our results may improve the understanding of the mechanisms of metals deposited on graphene and pave the way for future spintronic applications of Fe/graphene systems.
