Outline of Final Research Achievements

The graphene cousin of group IV materials; silicene and germane, are possible to be synthesize only by the epitaxial growth on substrate surfaces. However, on the conventional Ag(111) substrate surfaces, we found that the Si atoms are frequently exchanged with the substrate Ag atoms. It results in the complex growth mechanism which hinders the growth of the bilayer silicene. The strong electronic interaction also destroys the intrinsic Dirac electron nature of silicene on the Ag(111) substrate. In these respect, an alternative substrate with a weak interaction is of highly desired. We investigated the possibility of graphene as the substrate for the silicene growth. But, silicene was found not to grow on graphene. We further explored the direct growth of hBN on Si substrates for the versatile application of silicene and germane for their possible applications as the Si compatible electronic materials.
