Two of current surface-science topics will be outlined. First, we will see a
study of graphene formed on Pt(111) surfaces by thermal decomposition of
fullerene molecules. STM images reveal a variety of moire superstructures that
are successfully explained by a simple geometric model. The study also sheds
some light on the role of the preparation conditions and precursor on the
resulting structures.
Tailoring of self-organized formation of nanoparticles of more components
and variety of shape is one of the big challenges in nowadays nanotechnology. (více ...)
