Direct Measurement of Room-Temperature Nondiffusive Thermal Transport Over Micron Distances in a Silicon Membrane
Jeremy A. Johnson,Alexei Maznev,J. Cuffe,J. Cuffe,Jeffrey K. Eliason,Austin J. Minnich,Timothy Kehoe,Clivia M. Sotomayor Torres,Clivia M. Sotomayor Torres,Gang Chen,Keith A. Nelson +10 more
TL;DR: In this paper, a simple experiment demonstrating that room-temperature thermal transport in Si significantly deviates from the diffusion model already at micron distances is presented, indicating a transition from the diffusive to the ballistic transport regime for the low-frequency part of the phonon spectrum.

Thermal conductivities of two-dimensional graphitic carbon nitrides by molecule dynamics simulation
TL;DR: In this article, the thermal conductivities of three kinds of 2D graphitic carbon nitrides (2D GCNs) were investigated by non-equilibrium molecule dynamics (NEMD) simulations based on both Tersoff and ReaxFF potentials, which offer comprehensive understanding of their thermal properties.
