The temperature-dependence of carrier mobility is not a reliable indicator of the dominant scattering mechanism

Alex M. Ganose, Junsoo Park, Anubhav Jain

The temperature dependence of experimental charge carrier mobility is commonly used as a predictor of the dominant carrier scattering mechanism in semiconductors, particularly in t…

Globally Optimal Band Structure for Thermoelectrics in Realistic Systems

Junsoo Park

Observation is made that a linear dispersion in any dimension under acoustic-phonon-deformation-potential scattering theoretically prescribes a constant charge transport distributi…

Comparison of the Tetrahedron Method to Smearing Methods for the Electronic Density of States

M. Y. Toriyama, A. M. Ganose, M. Dylla +7

The electronic density of states (DOS) highlights fundamental properties of materials that oftentimes dictate their properties, such as the band gap and Van Hove singularities. In…

When Band Convergence is Not Beneficial for Thermoelectrics

Junsoo Park, Max Dylla, Yi Xia +3

Band convergence is considered a clear benefit to thermoelectric performance because it increases the charge carrier concentration for a given Fermi level, which typically enhances…

Leveraging Electron-Phonon Interaction to Enhance Thermoelectric Power Factor in Graphene-Like Semimetals

Yi Xia, Junsoo Park, Vidvuds Ozoliņš +1

Electron-phonon interaction (EPI) is presumably detrimental for thermoelectric performance in semiconductors because it limits carrier mobility. Here we show that enhanced EPI with…
