Limitations of zT as a Figure of Merit for Nanostructured Thermoelectric Materials
Xufeng Wang, Mark Lundstrom
A numerical study of thermoelectric nanocomposites is presented. Thermoelectric properties as a function of average grain size or nanoparticle density are examined by simulating th…
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…
On the Calculation of Lorenz Numbers for Complex Thermoelectric Materials
Xufeng Wang, Vahid Askarpour, Jesse Maassen +1
A first-principles informed approach to the calculation of Lorenz numbers for complex thermoelectric materials is presented and discussed. Example calculations illustrate the impor…
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…
Role of photon recycling in perovskite solar cells
Mohammad Ryyan Khan, Xufeng Wang, Reza Asadpour +2
Nearly perfect photon recycling helped GaAs cells achieve the highest efficiency ever reported for a solar cell. Recent reports of photon recycling in perovskite solar cells sugges…
