Thermal conductivity is one of the most fundamental properties of solid materials. The
thermal conductivity of ideal crystal materials has been widely studied over the past …

We review the status of research on thermal/phonon transport in disordered materials. The
term disordered materials is used here to encompass both structural and compositional …

Two different heat-transport mechanisms are discussed in solids. In crystals, heat carriers
propagate and scatter particlelike as described by Peierls's formulation of the Boltzmann …

High thermal conductivity materials show promise for thermal mitigation and heat removal in
devices. However, shrinking the length scales of these materials often leads to significant …

Amorphous silicon (a-Si) is an important thermal-management material and also serves as
an ideal playground for studying heat transport in strongly disordered materials. Theoretical …

Heat conduction in solids is typically governed by the Fourier's law describing a diffusion
process due to the short wavelength and mean free path for phonons and electrons. Surface …

Understanding the thermal properties of disordered systems is of fundamental importance
for condensed matter physics-and for practical applications as well. While quantities such as …

Dislocations, one-dimensional lattice imperfections, are common to technologically
important materials such as III–V semiconductors, and adversely affect heat dissipation in …

We discuss the role of atomic coordination in dictating the vibrational characteristics and
thermal conductivity in amorphous carbon. Our systematic atomistic simulations on …

The role of interfacial nonidealities and disorder on thermal transport across interfaces is
traditionally assumed to add resistance to heat transfer, decreasing the thermal boundary …
