The use of strain and grain boundaries to tailor phonon transport properties: A first principles study of 2H-phase (Part II)
Evan Witkoske, Zhen Tong, Yining Feng +3
Transparent oxide materials, such as , a p-type transparent conducting oxide (TCO), have recently been studied for high temperature thermoelectric power generators and c…
Homogenous alloys on ZnO substrates: A new approach for high performance thermoelectric materials
Yining Feng, Evan Witkoske, Bahadir Kucukgok +4
High performance thermoelectric materials for wide-range temperature applications still remains a challenge. In this study, we have produced high-quality homogeneous $In_{0.32}Ga_{…
The use of strain to tailor electronic thermoelectric transport properties: A first principles study of 2H-phase CuAlO2
Evan Witkoske, David Guzman, Yining Feng +3
Using first principles calculations, the use of strain to adjust electronic transport and the resultant thermoelectric (TE) properties is discussed using 2H phase CuAlO2 as a test…
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…
