The thermal conductivity of silicon nanowires can be altered by introducing different phonon scattering mechanisms. These scattering mechanisms manifest themselves as the dominant ones only in a certain range of frequency regimes. The study to control and modify the phonon thermal conductivity of nanowires via manipulating their internal structure, composition and defects is referred by the authors as “phononic engineering”. Phononic engineering will provide an efficient and practically useful tool for controlling the thermal conductivity of nanomaterials.
