First-Principles Calculation of Alloy Scattering and n-type Mobility in Strained GeSn
Kevin Sewell, Felipe Murphy-Armando
We use first-principles electronic-structure theory to determine the intra- and inter-valley electron-alloy scattering parameters in n-type GeSn alloys. These parameters are used t…
Enhancement of the electronic thermoelectric properties of bulk strained silicon-germanium alloys using the scattering relaxation times from first principles
F. Murphy-Armando
We use first-principles electronic structure methods to calculate the electronic thermoelectric properties (i.e. due to electronic transport only) of single-crystalline bulk -ty…
Ultrafast relaxation of symmetry-breaking photo-induced atomic forces
Shane M. O'Mahony, Felipe Murphy-Armando, Éamonn D. Murray +3
We present a first-principles method for the calculation of the temperature-dependent relaxation of symmetry-breaking atomic driving forces in photoexcited systems. We calculate th…
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,…
Deformation Potentials and Electron-Phonon Coupling in Silicon Nanowires
F. Murphy-Armando, G. Fagas, J. C. Greer
The role of reduced dimensionality and of the surface on electron-phonon (e-ph) coupling in silicon nanowires is determined from first principles. Surface termination and chemistry…
