Anomalous conduction mechanisms of Al-based stable quasicrystals

Abstract

Abstract We have analyzed the electrical conductivities of Al–Cu–Fe and Al–Cu–Ru quasicrystals in a low temperature region, taking into account the conducting mechanism of the quasicrystal-like system. The present analysis suggests strongly that not only the weak localization and the electron-electron interaction contributions but also the conducting effect of the quasicrystal-like system should be considered.
