Abstract
Quasicrystals exhibit low thermal and moderate electrical conductivity, acc ompanied by a relatively high absolute magnitude of thermopower, which make s them suitable candidates for use as thermoelectric devices. Theoretical e xplanations of electrical and thermal conductivity and thermopower of two r epresentative members of the Al-Cu-Fe icosahedral quasicrystal family (i-Al 62Cu25.5Fe12.5 and i-Al63Cu25Fe12) are given. Their figures of merit are re latively low compared with the best-known thermoelectric materials. (C) 200 1 Elsevier Science Ltd. All rights reserved.
