Abstract

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