Discussion of Electronic Properties of Quasicrystals

, 2008
International audienceThis article gives a short review of some important achievements in the field of electronic properties of quasicrystals. It focuses essentially on : the nature of quasicrystals as Hume-Rothery alloys, the energetics of quasicrystals

Evolution of superlattice order in Al-Mn quasicrystals and its relation to face-centred icosahedral quasicrystals

, 1989
We have established a simple icosahedral to face-centred icosahedral ordering transformation in Al-Mn quasicrystals. This result strongly supports the view that the recently discovered face-centred icosahedral quasicrystal in ternary Al-Cu-Fe and related

Elastic Green's function of icosahedral quasicrystals

, 1998
The elastic theory of quasicrystals considers, in addition to the "normal" displacement field, three "phason" degrees of freedom. We present an approximative solution for the elastic Green's function of icosahedral quasicrystals, assuming that the ...

Electronic structure of quasicrystals

, 2005
Quasicrystals are aperiodically ordered solids. Their unusual transport properties, especially the low electric conductivity, are indications of the particular electronic structure of these materials. There are several approaches toward understanding the

High-harmonic spectroscopy of mobility edges in one-dimensional quasicrystals

New Journal of Physics
Quasicrystals occupy a unique position between periodic and disordered systems, where localization phenomena such as Anderson transitions and mobility edges (MEs) can emerge even in the absence of disorder.

Decagonal quasicrystals

, 1989
Following the discovery of two dimensional quasicrystals in rapidly solidified Al-Mn alloys by us and L. Bendersky in 1985, a number of fascinating studies has been conducted to unravel the atomic configuration of quasicrystals with decagonal symmetry. A

Mesoscale field theory for quasicrystals

Physical Review Research
We present a mesoscale field theory unifying the modeling of growth, elasticity, and dislocations in quasicrystals. The theory is based on the amplitudes entering their density-wave representation.

Quasicrystals

, 1999
Created by Dr.Steffen Weber, the Quasicrystals Web site provides an introduction to this relatively new field of crystallography. Although much of the site is highly technical, those interested in related subjects will find exploring the thorough ...
