TLDR
In this paper, the authors explore electron filtering as a technique to increase the Seebeck coefficient and the thermoelectric power factor of heterostructured materials over that of the bulk.Abstract:
In this paper, we explore electron filtering as a technique to increase the Seebeck coefficient and the thermoelectric power factor of heterostructured materials over that of the bulk We present a theoretical model in which the Seebeck coefficient and the power factor can be increased in an ${\mathrm{In}}_{053}{\mathrm{Ga}}_{047}\mathrm{As}$-based composite material Experimental measurements of the cross-plane Seebeck coefficient are presented and confirm the importance of the electron filtering technique to decouple the electrical conductivity and Seebeck coefficient to increase the thermoelectric power factorread more

Approaching high-performance of ordered structure Sb 2 Te 3 film via unique angular intraplanar grain boundaries
TL;DR: It has been found that the electric field can induce the change in the angle of intraplanar grain boundaries between (0 1 5) and (01 5) planes, which leads to the enhanced holes mobility and maintained low thermal conductivity.
Structural and Thermoelectric Properties of Binary and Ternary Skutterudite Thin Films
TL;DR: In this article, the structural and thermoelectric properties of single-phase skutterudite thin films were investigated by taking the thermal stability of the film and the substrate properties into account.
