| Abstract(in English) | Two dimensional (2D) honeycomb crystals such as silicene and germanene are currently receiving much attention because of its exceptional electronic properties. We have studied the growth of such 2D crystals using the segregation of Si (or Ge) on the Ag surface by the annealing of Ag/Si(or SiGe, Ge) structure. An Ag(111) layer was epitaxially grown on Si(111), Ge(111), and SiGe(111) substrate by thermal evaporation, and the chemical and thermal stability of Ag surface were systematically evaluated to get the atomically flat Ag surface. After the annealing of Ag/Ge(111) structure at 450℃ in N2 ambience, segration of Ge atoms with an average thickness of bi-layer on the atomically flat Ag surface were observed from the analyses of AFM and HAXPES measurements. |
