General invariance and equilibrium conditions for lattice dynamics in 1D, 2D, and 3D materials
Changpeng Lin, Samuel Poncé, Nicola Marzari
The long-wavelength behavior of vibrational modes plays a central role in carrier transport, phonon-assisted optical properties, superconductivity, and thermomechanical and thermoe…
Accurate prediction of Hall mobilities in two-dimensional materials through gauge-covariant quadrupolar contributions
Samuel Poncé, Miquel Royo, Marco Gibertini +2
Despite considerable efforts, accurate computations of electron-phonon and carrier transport properties of low-dimensional materials from first principles have remained elusive. By…
Anisotropic-strain-enhanced hole mobility in GaN by lattice matching to ZnGeN and MgSiN
Joshua Leveillee, Samuel Ponce, Nicholas L. Adamski +2
The key obstacle toward realizing integrated gallium nitride (GaN) electronics is its low hole mobility. Here, we explore the possibility of improving the hole mobility of GaN via…
