Abstract
In this work we review the physical motivations, both experimental and theoretical, suggesting the possible use of quasicrystals as thermoelectric materials. Analytical expressions for the dimensionless thermoelectric figure of merit and the compatibility factor are discussed in order to optimize the thermoelectric performance of quasicrystals and their approximants. The potential of AlPd(Mn, Re) family is analysed within the context of current thermoelectric materials research.
