Electrical resistivity and Seebeck coefficient of hot-pressed YbAl3 over the temperature range 150-700K

Abstract YbAl specimens were prepared using a hot-pressing technique and the 3 Seebeck coefficient and electrical resistivity measured over the temperature range 150-700 K in order to assess their potential as thermoelectric materials. The preliminary results show that YbAl possesses an electrical power factor 3 double those of the state-of-the-art thermoelectric materials based on Bi Te 2 3 alloys which are employed over the range around room temperature and is a promising candidate material for thermoelectric generation using 'lowtemperature' waste heat.
