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…

Ultimate confinement of phonon propagation in silicon nano-crystalline structure
Takafumi Oyake, Lei Feng, Takuma Shiga +3
Temperature-dependent thermal conductivity of epitaxial silicon nano-crystalline (SiNC) structures composed of nanometer-sized grains separated by ultra-thin silicon-oxide (SiO2) f…
