Abstract

Thin 2200 angstroms icosahedral films with compositions near Al72Pd20Re8 have been fabricated on quartz glass substrates. Some of the films exhibited insulating transport properties down to 0.07 K where their resistivities followed an activated `Mott' variable-range hopping law. Other films exhibited metallic transport properties. In addition, the precursor amorphous AlPdRe films were observed to make superconducting transitions below 0.6 K; thus the amorphous and icosahedral structures exhibit contrasting metallic and insulating transport behaviours.
