(1) During this research period we have successfully grown honeycomb 2D silicon nitride layer on SiC(0001) surface. The structure of the surface has been determined by low-energy electron diffraction (LEED) analysis and match the one previously predicted by calculation. The results are also confirmed by scanning-tunneling microscopy (STM) measurements.(2) According to research plan we intended also to try the growth of nanostructures using vicinal stepped surfaces of SiC. In anticipation of it, we have investigated the morphology and step dynamics of vicinal SiC. This was accompanied with study of graphene growth on the surface.(3) New computational approaches (tight-binding models with unfolded band structure calculations) are in development to deepen insights.
