Anisotropic Effects on the Thermoelectric Properties of Highly Oriented Electrodeposited Bi(2)Te(3) Films

Highly oriented [1 1 0] Bi(2)Te(3) films were obtained by pulsed electrodeposition. The structure, composition, and morphology of these films were characterized. The thermoelectric figure of merit (zT), both parallel and perpendicular to the substrate surface, were determined by measuring the Seebec...

Sumario:Highly oriented [1 1 0] Bi(2)Te(3) films were obtained by pulsed electrodeposition. The structure, composition, and morphology of these films were characterized. The thermoelectric figure of merit (zT), both parallel and perpendicular to the substrate surface, were determined by measuring the Seebeck coefficient, electrical conductivity, and thermal conductivity in each direction. At 300 K, the in-plane and out-of-plane figure of merits of these Bi(2)Te(3) films were (5.6 ± 1.2)·10(−2) and (10.4 ± 2.6)·10(−2), respectively.
