Journal ArticleDOI
Thermoelectric power factor: Enhancement mechanisms and strategies for higher performance thermoelectric materials
TL;DR: In this article, the authors discuss the ideas and strategies proposed and developed in order to improve the thermoelectric power factor and thus hopefully move us closer to the target of a ZT < 2.
Journal ArticleDOI
Large Thermoelectric Power Factor in Pr-Doped SrTiO3−δ Ceramics via Grain-Boundary-Induced Mobility Enhancement
Arash Mehdizadeh Dehkordi,Sriparna Bhattacharya,Taghi Darroudi,Jennifer Graff,Udo Schwingenschlögl,Husam N. Alshareef,Terry M. Tritt +6 more
TL;DR: In this paper, a novel synthesis strategy to prepare high-performance bulk polycrystalline Pr-doped SrTiO3 ceramics was reported, which achieved a large thermoelectric power factor of 1.3 W m −1 K −1 at 500 °C. This significant improvement results from a substantial enhancement in carrier mobility originating from the formation of Pr-rich grain boundaries.
Journal ArticleDOI
The effect of synthesis parameters on transport properties of nanostructured bulk thermoelectric p-type silicon germanium alloy
TL;DR: In this article, the Boltzmann transport equation was used to calculate the electrical and thermal properties of nanostructured p-type SiGe alloys and the effect of various parameters of milling process and sintering conditions on the thermoelectric properties of the grown samples were studied.
Journal ArticleDOI
Significant enhancement in thermoelectric properties of polycrystalline Pr-doped SrTiO3−δ ceramics originating from nonuniform distribution of Pr dopants
TL;DR: In this paper, the authors investigated the electronic and thermal transport in Sr1−xPrxTiO3 ceramics in order to determine the optimum doping concentration and to evaluate the overall thermoelectric performance.
Journal ArticleDOI
Enhanced thermoelectric figure-of-merit in thermally robust, nanostructured superlattices based on SrTiO3
Anas Abutaha,S. R. Sarath Kumar,Kun Li,Arash Mehdizadeh Dehkordi,Terry M. Tritt,Husam N. Alshareef +5 more
TL;DR: In this paper, the authors report the TE properties of metal oxide superlattices, composed from alternating layers of 5% Pr3+doped SrTiO3−δ (SPTO) and 20% Nb5+-doped STiO 3−ε (STNO), fabricated using pulsed laser deposition (PLD).
