From photonic to phononic: Toward heat transfer control by MEMS nanostructures

There are some physical similarities in photonics and phononics; photon and phonon transports can be coherently controlled by micro/nanoscale artificial crystal structures. Similarities and non-similarities of two photon and phonon transports will be discussed and we focus on the coherent manipulation of phonon transport by phononic crystal nanostructures. We also discuss possibility of thermal conduction nanoengineering with some simulation results in silicon at room temperature. The multiple scale physics in phononic systems makes phonon transport control, which is heat transfer, more difficult, but some challenges to accomplish the goal will be shown.
