Study of phonon transmission through solid-solid interfaces and superlattices by phonon imaging
… the low-temperature propagation of heat pulses (phonons) through crystals and across solid-solid interfaces. The phonon imaging technique has been used to examine the angular and temporal dependence of the phonon-flux intensity in several systems, listed below. 1. Phonon focusing in cubic …

Computational Modeling of Geometry Dependent Phonon Transport in Silicon Nanostructures
… depend on nanostructure boundary geometry. Phonons are quantized mechanical vibrations that are the dominant carrier of heat in semiconductor materials and their aggregate behavior determine a nanostructure's thermal performance. Phonon-geometry scattering processes as well as waveguiding …

Atomistic and mesoscopic simulations of heat transfer across heterogeneous material interfaces
… techniques that enable spectrally-resolved phonon transport measurements at the nanoscale along with the development of high-fidelity simulation methods have provided a renewed interest in the fundamental physics of heat transfer across interfaces. Miniaturized electronic devices and …

Exploring heat transfer at the atomistic level for thermal energy conversion and management
… introduce atomistic techniques to investigate phonon transport in bulk crystals. We start with normal mode analysis within the classical molecular dynamics framework to estimate the spectral phonon transport properties. Although it can provide the detailed phonon properties adequately, …

Investigation on fabrication, interface formation, and properties of hot-processed titanium-doped copper/diamond composites
… affinity between copper and diamond and severe phonon scattering due to mismatched lattice vibrations. To address these challenges, interface engineering strategies such as pre-coating diamond particles or pre-alloying the copper matrix with carbide-forming elements (e.g., Ti, W, Zr, Cr, B) have …
