摘要：

Samples of icosahedral AlPdRe have been studied for a range of varying resistance ratios R=rho(4.2 K)/rho(295 K). Structural characterization techniques used include x-ray diffraction, scanning electron microscopy, and diffraction in transmission electron microscopy. The electrical resistance was measured down to 40 mK. The conductivity at T=0 K, sigma(0), extrapolated from these results was nonzero for all samples and sigma(0) was found to decrease exponentially with increasing R over more than an order of magnitude in sigma(0).
