A5: Nanoscale and low dimensional effects
Birck Nanotechnology Center, Purdue University
Fourier diffusion equation has been used very successfully to describe heat transport in
materials with embedded nanostructures. In this talk we describe some of the recent
studies of ballistic heat transport where a frequency-dependent thermal conductivity has been introduced. We show that trunctated Levy flight can provide an alternative explanation based on heat superdiffusion at small length scales. Implications in the design of nanostructured materials for thermoelectrics will be described.
