Özet:

 

We have generated cubic Al alloys as commensurate single  crystals on the tenfold-symmetry surface of the quasicrystalline  Al-Ni-Co alloy by ion bombarding its surface.  We find that the  crystal-quasicrystal interface contains several alignments of mutual  high-symmetry directions and planes.  In order to explore the structural matching conditions at the  crystal-quasicrystal interface, we have grown Al films on the  decagonal surface of Al-Ni-Co by vapor deposition.  The initial growth  mode of Al is commensurate.  As the coverage is increased, Al starts  to grow in cubic textures breaking into multi-twinned, few-nanometer-  large domains.  The symmetry of the substrate determines thereby the  orientation of the domains, while the degree of structural mismatch  between the crystal and the quasicrystal limits the domain size.
