Influence of chemical disorder, magnetic field and phason flips on the localization of electronic states in a regular icosahedral quasicrystal

The influence of substitutional chemical disorder, magnetic field and phasons, on the electronic spectrum and wave functions of icosahedral quasicrystals is investigated by means of tight-binding approximation and level statistic method. The results show that the localization of electronic states in...

Summary:The influence of substitutional chemical disorder, magnetic field and phasons, on the electronic spectrum and wave functions of icosahedral quasicrystals is investigated by means of tight-binding approximation and level statistic method. The results show that the localization of electronic states in an ideal quasicrystal exists due to their coherent interference at the Fermi level which is caused by the symmetry and aperiodic long-range order.
