Graphene is being considered as a contender as the reference material with extraordinary properties for a post-CMOS technology.The novel properties of graphene honeycomb structure have spurred tremendous interest in investigating other two-dimensional(2D)layered structures beyond graphene.In this talk,besides high quality and large scale single crystal graphene on metal surfaces,we will report the epitaxial fabrication of two kinds of graphene-like materials,silicene and hafene,wherein silicon atoms or Hf atoms are substituted for carbon atoms in graphene.The stacking heterolayersbased on these kinds of 2D crystalline materials will be also introduced.As-prepared graphene/Si(or Hf)/metal architectureswere characterized by scanning tunneling microscopy/spectroscopy(STM/STS),Raman,and angle resolved electron photoemission spectroscopy(ARPES)and proves the high structural and electronic qualities of the new complex.
