Space-time dependent thermal conductivity in nonlocal thermal transport

Abstract

Here, a direct solution is provided of a time-space-dependent Peierls-Boltzmann equation with a linearized collision matrix. This will expand the state-of-the-art of thermal transport prediction and provide an avenue for understanding novel nonlocal transport measurements. Application ofmethodology developed here will illuminate physical insights into length and time scale dependent transport behavior in ultrahigh thermal conductivity materials, thus guiding interpretation of measurements and enabling critical understanding of materials for design of novel thermal management applications.
