Journal ArticleDOI
Orbitally driven giant phonon anharmonicity in SnSe
Chen Li,Jiawang Hong,Andrew F. May,Dipanshu Bansal,Songxue Chi,Tao Hong,Georg Ehlers,Olivier Delaire +7 more
TL;DR: In this article, a microscopic picture connecting electronic structure and phonon anharmonicity in SnSe is provided, and offers new insights on how electron-phonon interactions may lead to the realization of ultralow thermal conductivity.
Journal ArticleDOI
Metallization of vanadium dioxide driven by large phonon entropy
John D. Budai,Jiawang Hong,Michael Manley,Eliot D. Specht,Chen Li,Jonathan Z. Tischler,Douglas L. Abernathy,Ayman Said,Bogdan M. Leu,Lynn A. Boatner,Robert J. McQueeney,Olivier Delaire +11 more
TL;DR: The critical role of anharmonic lattice dynamics in metal oxide phase competition is illustrated, which provides guidance for the predictive design of new materials and how a balance between higher entropy in the metal and orbital-driven lower energy in the insulator fully describes the thermodynamic forces controlling the MIT.
Journal ArticleDOI
Structural Relationship between Negative Thermal Expansion and Quartic Anharmonicity of Cubic ScF 3
TL;DR: Phonon calculations with first-principles methods identified the individual modes in the densities of states, and frozen phonon calculations showed that some of the modes with motions of F atoms transverse to their bond direction behave as quantum quartic oscillators.
Journal ArticleDOI
Phonon self-energy and origin of anomalous neutron scattering spectra in SnTe and PbTe thermoelectrics
Chen Li,Olle Hellman,Jie Ma,Andrew F. May,Huibo Cao,Xing-Qiu Chen,Andrew D. Christianson,Georg Ehlers,David J. Singh,Brian C. Sales,Olivier Delaire +10 more
TL;DR: In this article, the anharmonic lattice dynamics of rock-salt thermoelectric compounds SnTe and PbTe were investigated with inelastic neutron scattering (INS) and first-principles calculations.
Journal ArticleDOI
Phonon anharmonicity and negative thermal expansion in SnSe
Dipanshu Bansal,Jiawang Hong,Chen Li,Andrew F. May,Wallace D. Porter,Michael Y. Hu,Douglas L. Abernathy,Olivier Delaire,Olivier Delaire +8 more
TL;DR: In this article, the anharmonic phonon properties of SnSe in the $Pnma$ phase were investigated with a combination of experiments and first-principles simulations.
