Heat Transfer in Nanostructured Si and Heat Flux Control Technique

Heat transfer in Si nanostructure is not only an interesting topic in fundamental physics, but also an important practical study for efficient heat dissipation in electronic devices. In this paper, we discuss characteristic thermal phonon transport property in nanostructured Si membranes, where the dimension is smaller than phonon mean free path. We mainly focus on heat flux control technique in Si membranes using ballisticity and wave nature of phonons, which may be useful for deeper understanding of thermal dissipation in electronic devices with nanostructures.
