These lectures provide a theoretical development of the transport of thermal energy by conduction in nanomaterials, in which material interfaces typically dominate transport. The physical nature of energy transport by two carriers: electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the quantum of thermal conductance, ballistic interface resistance, and carrier scattering will be developed. Bulk material properties, such as thermal conductivity, will be derived from particle transport theories, and the effects of spatial confinement and material interfaces on these properties will be established.

“Electronics from the Bottom Up” is an educational initiative designed to bring a new perspective to the field of nano device engineering. It is co-sponsored by the Intel Foundation and the Network for Computational Nanotechnology.
