Phonon quarticity induced by changes in phonon-tracked hybridization during lattice expansion and its stabilization of rutile TiO
Tian Lan, C. W. Li, O. Hellman +5
Although the rutile structure of TiO is stable at high temperatures, the conventional quasiharmonic approximation predicts that several acoustic phonons decrease anomalously to…

Phonon self-energy and origin of anomalous neutron scattering spectra in SnTe and PbTe thermoelectrics
C. W. Li, O. Hellman, J. Ma +8
The anharmonic lattice dynamics of rock-salt thermoelectric compounds SnTe and PbTe are investigated with inelastic neutron scattering (INS) and first-principles calculations. The…
