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…
