Thermal transport at the nanoscale level is attracting attention not only because of its
physically interesting features such as the peculiar behavior of phonons due to their …

Understanding and controlling vibrations in condensed matter is emerging as an essential
necessity both at fundamental level and for the development of a broad variety of …

The design and fabrication of phononic crystals (PnCs) hold the key to control the
propagation of heat and sound at the nanoscale. However, there is a lack of experimental …

Knowledge of the mean-free-path distribution of heat-carrying phonons is key to
understanding phonon-mediated thermal transport. We demonstrate that thermal …

The central concept in phononics is the tuning of the phonon dispersion relation, or phonon
engineering, which provides a means of controlling related properties such as group velocity …

A detailed understanding of the connections of fabrication and processing to structural and
thermal properties of low-dimensional nanostructures is essential to design materials and …

The classical Fourier's law fails in extremely small and ultrafast heat conduction even at
ordinary temperatures due to strong thermodynamic nonequilibrium effects. In this work, a …

Heat conduction in silicon can be effectively engineered by means of sub-micrometre
porous thin free-standing membranes. Tunable thermal properties make these structures …

The degree of thermal anisotropy affects critically key device-relevant properties of layered
two-dimensional materials. Here, we systematically study the in-plane and cross-plane …

We investigate the impact of various phonon-scattering mechanisms on the in-plane thermal
conductivity of suspended silicon thin films with two-dimensional periodic arrays of holes, ie …
