Thermal conductivity inhibition in phonon engineered core-shell cross-section modulated Si/Ge nanowires

(author unknown)



Denis L. Nika, Alexandr I. Cocemasov, and Dmitrii V. Crismari et al.

We have shown theoretically that a combination of cross-section modulation and acoustic mismatch in the core-shell Si/Ge nanowires can lead to a drastic reduction of the thermal conductivity. Our calculations, which utilized two different models–five-parameter Born-von Karman and six-parameter val ... [Appl. Phys. Lett. 102, 213109 (2013)] published Wed May 29, 2013.
