By considering a suitable model for the spectral conductivity we show that high values of the thermoelectric figure of merit, beyond the practical upper limit ZT=1, may be expected for certain quasicrystalline alloys. We also study their performance at different working temperature ranges, favoring low temperature thermoelectric applications for these materials. By comparing our analytical results with available experimental data on the transport coefficients of different quasicrystalline families. we suggest the icosahedral Cd-Yb and the dodecagonal Ta-Te binary phases as two promising candidates for further research. 1098-0121 10.1103/PhysRevB.64.094206 https://hdl.handle.net/20.500.14352/60193 http://dx.doi.org/10.1103/PhysRevB.64.094206 https://journals.aps.org Theoretical prospective of quasicrystals as thermoelectric materials
