Revisiting PbTe to identify how thermal conductivity is really limited
Shenghong Ju, Takuma Shiga, Lei Feng +1
Due to the long range interaction in lead telluride (PbTe), the transverse optical (TO) phonon becomes soft around the Brillouin zone center. Previous studies have postulated that…

Phonon-interference resonance effects in nanoparticles embedded in a matrix
Lei Feng, Takuma Shiga, Haoxue Han +3
We report an unambiguous phonon resonance effect originating from germanium nanoparticles embedded in silicon matrix. Our approach features the combination of phonon wave-packet me…

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…
