Local configurations on surfaces of icosahedral quasicrystals

Abstract

The surfaces of icosahedral quasicrystals of an F-phase, orthogonal to a fivefold symmetry axis have a terrace-like appearance. On highly resolved images of these terraces one observes different local configurations. We search for possible corresponding configurations in the bulk model of atomic positions. based on the icosahedral tiling *(2 F ).
