TL;DR: A simple experiment demonstrates that room-temperature thermal transport in Si significantly deviates from the diffusion model already at micron distances, indicating a transition from the diffusive to the ballistic transport regime for the low-frequency part of the phonon spectrum.

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.

TL;DR: In this paper, the authors measured lattice swelling and elastic modulus changes in a W-1% Re alloy after implantation with 3110 amp of helium and applied a multiscale model, combining elasticity and density functional theory, to the interpretation of observations.

TL;DR: In this article, thermal conductivity measurements of thin Si membranes spanning a wide thickness range were used to characterize how bulk thermal conductivities are distributed over phonon mean free paths, and a noncontact transient thermal grating technique was used to measure the thermal conductive of suspended Si membranes ranging from 15-1500 nm in thickness.

TL;DR: The measured dispersion curves exhibit "avoided crossing" behavior due to the hybridization of the SAWs with the microsphere resonance, and are compared with those predicted by the analytical model and find excellent agreement.
