ELECTRONIC TRANSPORT-PROPERTIES OF QUASI-CRYSTALS

We present a review of some results concerning electronic transport pr operties of quasicrystals. After a short introduction to the basic con cepts of quasiperiodicity, we consider the experimental transport prop erties of electrical conductivity with particular focus on the effect of temperature, magnetic field, and defects. Then, we present some heu ristic approaches that tend to give a coherent view of different, and to some extent complementary, transport mechanisms in quasicrystals. N umerical results are also presented and in particular the evaluation o f the linear response Kubo-Greenwood formula of conductivity in quasip eriodic systems in the presence of disorder.
