摘要：
The electronic structures in realistic quasicrystals are discussed theoretically. The density of states consists of a set of spiky peaks with widths of order 0.02 eV and has pseudogaps at the Fermi energy with widths of order 1 eV. The Boltzmann theory based on the detailed band structures would predict very high values of resistivity. The temperature dependence of the observed thermoelectric power may be due to the spiky peak structures of the conductivity as a function of the Fermi energy.
