By considering a realistic model for the spectral conductivity we derive closed analytical expressions for the transport coefficients which allow us to study the temperature dependence of the Lorenz ratio L( T) = κ_(e)(T)/ Tσ( T) at different temperature regimes. We conclude that quasicrystals closely follow Wiedemann- Franz's law over a wide temperature range.engjournal articlehttp://dx.doi.org/10.1063/1.1488696http://aip.scitation.orgopen access538.9Al-Cu-FeElectronic transport-propertiesIcosahedral quasi-crystalsDensity-of-statesThermoelectric-materialsConductivityClustersAlloysPhasesFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
