Abstract

We report the first surface characterization of a large, single-grain sample of quasicrystalline AlCuFe. The sample is oriented with its surface perpendicular to a five-fold axis, and has the bulk composition 63.4-24.0-12.6 at%. Following our method of preparation, the surface yields an exceptionally sharp and rich five-fold pattern in low-energy electron diffraction. The spot spacings and symmetries are consistent with expectations for this surface, based upon the unreconstructed structure.
