Effects of Intermixing in Sb₂Te₃/Ge_1+xTe Multilayers on the Thermoelectric Power Factor.

ABSTRACT: Over the past few decades, telluride-based chalcogenide multilayers, such as PbSeTe/PbTe, Bi₂Te₃/Sb₂Te₃, and Bi₂Te₃/Bi₂Se₃, were shown to be promising high-performance thermoelectric films. However, the stability of performance in operating environments, in particular, influenced by intermixing of the sublayers, has been studied rarely. In the present work, the nanostructure, thermal stability, and thermoelectric power factor of Sb₂Te₃/Ge_1+xTe multilayers prepared by pulsed laser deposition are investigated by transmission electron microscopy and Seebeck coefficient/electrical conductivity measurements performed during thermal cycling.
