Dominant electron-phonon scattering mechanisms in -type PbTe from first principles
Jiang Cao, Jose D. Querales-Flores, Aoife R. Murphy +2
We present an \emph{ab-initio} study that identifies the main electron-phonon scattering channels in -type PbTe. We develop an electronic transport model based on the Boltzmann…

Acoustic Deformation Potentials of -Type PbTe from First Principles
Aoife R. Murphy, Felipe Murphy-Armando, Stephen Fahy +1
We calculate the uniaxial and dilatation acoustic deformation potentials, and , of the conduction band L valleys of PbTe from first principles,…

Acoustic-Soft Optical Mode Coupling Leads to Negative Thermal Expansion of GeTe near the Ferroelectric Phase Transition
Đorđe Dangić, Aoife R. Murphy, Éamonn D. Murray +2
GeTe is a well-known ferroelectric and thermoelectric material that undergoes a structural phase transition from a rhombohedral to the rocksalt structure at K. We pr…
