The authors report the measurement of the thermal conductivity, electrical resistivity, and thermoelectric power on two quasicrystalline compounds, Al{sub 70}Pd{sub 20}Re{sub 10} and Al{sub 62.5}Cu{sub 25}Fe{sub 12.5}. These materials are found to possess a thermal conductivity of order 1 W/m{center{underscore}dot}K, while retaining their semimetallic conductivity. These features coupled with moderately large thermopowers, up to 55 {micro}V/K, imply that the general class of quasicrystalline compounds warrants careful investigation for their potential as new thermoelectric materials.
