ADVANCES IN THERMOPHYSICAL PROPERTIES AT NANOSCALE IN CHINA
In this paper, we have summarized the progress in the studies of the thermophysical properties at nanoscale in China. The review contains five major parts: nanotube and nanowire, nanofilm, interface, nano-functional material, near field radiation. One-dimensional steady-state electrical heating method, T type probe method, 3ω method, femtosecond laser pump-probe method and photothermal reflectance method are powerful tools for experimentally measuring thermophysical properties of such nanostructures. Atomic-level simulation based on the Boltzmann transport equation (BTE) and phonon scattering relations is another approach to calculate thermophysical properties. Currently, many studies focus on searching for approaches to solving the BTE for various nanostructures. Interfaces are a key issue that should be considered on very small scales. The effects of many solid-solid interfaces in the superlattice structures have been studied by the molecular dynamics simulation and experimental methods. Furthermore, a frontier issue in heat transport is near-field radiation problem, which emerges when the gap between two objects is close to nanometers. The research in this field is in its infancy and only rare simulation results are available.
