$A novel model for electronic transport in quasicrystals is proposed. The electronic relaxation time due to scattering by structural and phase disorder and quasilattice vibrations is calculated on the assumption that a multivalley fractional Fermi surface exists in the icosahedral phases. Then some kinetic characteristics like the electrical conductivity and thermopower are evaluated over a wide temperature range on the basis of the fractional Fermi surface model. The calculated transport properties exhibit the main experimentally observed features of quasicrystals, such as the low density of states at the Fermi level, the low value of the electrical conductivity at zero temperature and its square-root temperature dependence at low temperatures, and the large absolute value and strong temperature dependence of the thermopower, © <i>1995 American Institute of Physics.</i>$
