Abstract

We have conducted a computer simulation of thermoelectric (TE) properties in tilted Cu / Fe 2 V (Al 0.9 Si 0.1) multilayers. Such a tilted configuration yields a transverse (off-diagonal) TE effect whereby an electric current can flow perpendicularly to the temperature gradient. Appropriately controlling the relative Cu thickness and the tilting angle realizes a higher power factor than that of the parent TE materials. In our multilayers, the estimated power factor exceeds 8 mW / K 2 m, being approximately three times higher than that of the parent TE materials. On the basis of the simulation results, we have fabricated several modules and achieved a maximum power of 4.83 mW in the module with a relative Cu thickness of 0.7 and a tilting angle of 30 °.
