Epitactic textures of fcc Al on icosahedral Al-Pd-Mn quasicrystal - art. no. 052203

An aluminum film is deposited on the fivefold-symmetric surface of icosahed ral Al-Pd-Mn quasicrystal. Its orientation with respect to the bulk structu re is studied using low-energy electron diffraction. It is found that Al na nocrystals grow in the face-centered cubic structure in five different sets of domains composing the film, and that their [111] axes are aligned paral lel to one of five threefold-symmetry axes of the substrate quasicrystal at 37.37 degrees away from the surface normal.
