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…

Temperature dependent effective third order interatomic force constants from first principles
Olle Hellman, Igor A. Abrikosov
The temperature dependent effective potential (TDEP) method is generalized beyond pair interactions. The second and third order force constants are determined consistently from ab…
