Ultrafast measurements of mode-specific deformation potentials of BiTe and BiSe
Yijing Huang, José D. Querales-Flores, Samuel W. Teitelbaum +24
Quantifying electron-phonon interactions for the surface states of topological materials can provide key insights into surface-state transport, topological superconductivity, and p…
Temperature induced band convergence, intervalley scattering and thermoelectric transport in p-type PbTe
Ransell D'Souza, José D. Querales-Flores, Jiang Cao +2
Achieving high valley degeneracy (i.e. "band convergence") in a material usually results in considerably enhanced thermoelectric properties. However, it is still unclear why this s…
Electron-phonon coupling and electronic thermoelectric properties of n-type PbTe driven near the soft-mode phase transition via lattice expansion
Jiang Cao, Đorđe Dangić, José D. Querales-Flores +2
IV-VI materials are some of the most efficient bulk thermoelectric materials due to their proximity to soft-mode phase transitions, which leads to low lattice thermal conductivity.…
Towards Accurate Predictions of Carrier Mobilities and Thermoelectric Performances in 2D Materials
Yu Wu, Bowen Hou, Ying Chen +9
The interactions between electrons and lattice vibrational modes play the key role in determining the carrier transport properties, thermoelectric performance and other physical qu…
Electron-phonon scattering and thermoelectric transport in -type PbTe from first principles
Ransell D'Souza, Jiang Cao, José D. Querales-Flores +2
We present a first principles based model of electron-phonon scattering mechanisms and thermoelectric transport at the L and valleys in <200b>-type PbTe, accounting for thei…
Towards temperature-induced topological phase transition in SnTe: A first principles study
José D. Querales-Flores, Pablo Aguado-Puente, Đorđe Dangić +6
The temperature renormalization of the bulk band structure of a topological crystalline insulator, SnTe, is calculated using first principles methods. We explicitly include the eff…
