Long-range quadrupole electron-phonon interaction from first principles
Jinsoo Park, Jin-Jian Zhou, Vatsal A. Jhalani +2
Lattice vibrations in materials induce perturbations on the electron dynamics in the form of long-range (dipole and quadrupole) and short-range (octopole and higher) potentials. Th…
Piezoelectric Electron-Phonon Interaction from Ab Initio Dynamical Quadrupoles: Impact on Charge Transport in Wurtzite GaN
Vatsal A. Jhalani, Jin-Jian Zhou, Jinsoo Park +2
First-principles calculations of -ph interactions are becoming a pillar of electronic structure theory. However, the current approach is incomplete. The piezoelectric (PE) -p…
Precise Radiative Lifetimes in Bulk Crystals from First Principles: The Case of Wurtzite GaN
Vatsal A. Jhalani, Hsiao-Yi Chen, Maurizia Palummo +1
Gallium nitride (GaN) is a key semiconductor for solid-state lighting, but its radiative processes are not fully understood. Here we show a first-principles approach to accurately…
Ab Initio Calculations of Exciton Radiative Lifetimes in Bulk Crystals, Nanostructures and Molecules
Hsiao-Yi Chen, Vatsal A. Jhalani, Maurizia Palummo +1
Excitons are bound electron-hole pairs that dominate the optical response of semiconductors and insulators, especially in materials where the Coulomb interaction is weakly screened…
