The electrical conductivity of single-grain Al–Pd–Re quasicrystals

Abstract

Abstract Systematic electrical transport data are presented for single quasicrystals in the Al–Pd–Re family across the accessible width of formation. The temperature dependence of the electrical conductivity can be accounted for in terms of weak localization and electron-electron interactions for all compositions studied, in contrast with previous studies of cast and annealed polygrain material. These results indicate that the conductivity mechanism in the Al–Pd–Re system is not dramatically different from that of other quasicrystal families.
