English abstract:
The atomic structure of the BaTiO3-derived 2D oxide quasicrystals (OQCs) is
investigated using scanning tunneling microscopy (STM) and noncontact atomic
force microscopy (nc-AFM). It is demonstrated that these extraordinary films can
easily be prepared as single-phase monolayers on a Pt(111) support. From
analyzing almost 20 000 atomic vertices, an extended statistical dataset of the
OQC tiling is collected. It manifests that the OQC obeys the statistics of the
Niizeki-Gähler tiling, which is a dodecagonal triangle-square-rhomb model
system. The atomic structure shown by nc-AFM is identical to the contrast
obtained in STM images. The results are discussed with respect to the existing
structural models.
