Anharmonic phonon effects on linear thermal expansion of trigonal bismuth selenide and antimony telluride crystals
Chee Kwan Gan, Ching Hua Lee
We adopted and extended an efficient Grüneisen formalism to study the phonon anharmonicity and linear thermal expansion coefficients (TECs) of trigonal bismuth selenide (BiSe$_…

Anharmonic interatomic force constants and thermal conductivity from Grüneisen parameters: an application to graphene
Ching Hua Lee, Chee Kwan Gan
Phonon-mediated thermal conductivity, which is of great technological relevance, fundamentally arises due to anharmonic scattering from interatomic potentials. Despite its prevalen…
