The Limits of Thermoelectric Performance with a Bounded Transport Distribution
Jesse Maassen
With the goal of maximizing the thermoelectric (TE) figure of merit , Mahan and Sofo [Proc. Natl. Acad. Sci. U.S.A. 93, 7436 (1996)] found that the optimal transport distributi…
Analysis of simple scattering models on the thermoelectric performance of analytical electron dispersions
Cameron Rudderham, Jesse Maassen
Recent first-principles electron-phonon scattering calculations of heavily-doped semiconductors suggest that a simple DOS scattering model, wherein the electronic scattering rates…
Unusual thermoelectric transport anisotropy in quasi-2D, rhombohedral GeTe
Vahid Askarpour, Jesse Maassen
In this study, we calculate the =300 K scattering and thermoelectric transport properties of rhombohedral GeTe using first-principles modeling. The room-temperature phase of GeT…
LanTraP: A code for calculating thermoelectric transport properties with the Landauer formalism
Xufeng Wang, Evan Witkoske, Jesse Maassen +1
A code for calculating the semi-classical thermoelectric and electronic transport properties is described. It uses the Landauer transport theory, which is equivalent to the Boltzma…
Universal Behavior of the Thermoelectric Figure of Merit, zT, vs. Quality Factor
Evan Witkoske, Xufeng Wang, Jesse Maassen +1
To increase the performance of thermoelectric materials, the electronic parameters in the figure of merit must be improved. In this paper, we use full, numerical band structures an…
Thermoelectric Band Engineering: The Role of Carrier Scattering
Evan Witkoske, Xufeng Wang, Vahid Askarpour +2
Complex electronic band structures, with multiple valleys or bands at the same or similar energies can be beneficial for thermoelectric performance, but the advantages can be offse…
