A brief review on the recent development of phonon engineering and manipulation at nanoscales

Abstract

Highlights The latest theoretical and experimental progress in phonon engineering at the nanoscale is summarized comprehensively in this review, which proposes avenues for future research in related fields. Phonon manipulation strategies and physical mechanisms of different thermophononic devices are sorted out and discussed in detail. The experimental methods and technical means involved in this article can provide guidance for the fabrication of thermal functional devices, hence promoting phononics from fundamental research to practical applications.
