Phonon transport in perovskite SrTiO3 from first principles
Lei Feng, Takuma Shiga, Junichiro Shiomi
We investigate phonon transport in perovskite strontium titanate (SrTiO3) which is stable above its phase transition temperature (~105 K) by using first-principles molecular dynami…
Probing and tuning inelastic phonon conductance across finite-thickness interface
Takuru Murakami, Takuma Hori, Takuma Shiga +1
Phonon transmission across an interface between dissimilar crystalline solids is calculated using molecular dynamics simulations with interatomic force constants obtained from firs…
Origin of anomalous anharmonic lattice dynamics of lead telluride
Takuma Shiga, Takuru Murakami, Takuma Hori +2
The origin of the anomalous anharmonic lattice dynamics of lead telluride is investigated using molecular dynamics simulations with interatomic force constants (IFCs) up to quartic…
Influence of mass contrast in alloy phonon scattering
Takuma Shiga, Takuma Hori, Junichiro Shiomi
We have investigated the effect of mass contrast on alloy phonon scattering in mass-substituted Lennard-Jones crystals. By calculating the mass-difference phonon scattering rate us…
