TLDR
In this article, a model for the decagonal phase of the Al13Fe4 system is proposed and the electronic structure is calculated within the tight-binding method, and results for the local and the integrated electronic density of states at particular sites are presented.Abstract:

Intrinsic defects in and electronic properties of θ-Al13Fe4: an ab initio DFT study
TL;DR: In this paper, the intrinsic defects in θ-Al13Fe4 were investigated using a first-principles density-functional theory method, which revealed that among the various intrinsic defects it is energetically favorable for Fe substitution of Al but on just three of the fifteen Al sites.

Metallic Phase with Long-Range Orientational Order and No Translational Symmetry
TL;DR: In this article, a metallic solid with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations, was observed and its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice.

Quasicrystal with one-dimensional translational symmetry and a tenfold rotation axis.
TL;DR: Studies of phase formation in rapidly solidified Al-Mn alloys show that an icosahedral phase is replaced by another noncrystallographic phase, a decagonal phase.

A quasicrystal structure model for AI-Mn
P. Guyot,Marc Audier +1 more
TL;DR: In this paper, a model for the atomic structure of the Al-Mn quasicrystal is proposed, where icosahedral symmetry and its projections onto various planes have a self-similarity property based on the golden number, in agreement with TEM results.

Universal pseudogap at Fermi energy in quasicrystals
Takeo Fujiwara,Takeshi Yokokawa +1 more
TL;DR: The electronic structures are calculated for several crystalline approximants of quasicrystals, AlCuLi and AlFe, and the densities of states of these systems, and also of AlMn, suggest universality of the pseudogap at the Fermi energy in quasICrystals.
