The Role of Thermalizing and Non-thermalizing Walls in Phonon Heat Conduction along Thin Films
Navaneetha K. Ravichandran, Austin J. Minnich
Phonon boundary scattering is typically treated using the Fuchs-Sondheimer theory, which assumes that phonons are thermalized to the local temperature at the boundary. However, whe…
Heat conduction in multifunctional nanotrusses studied using Boltzmann transport equation
Nicholas G. Dou, Austin J. Minnich
Materials that possess low density, low thermal conductivity, and high stiffness are desirable for engineering applications, but most materials cannot realize these properties simu…
Fresnel transmission coefficients for thermal phonons at solid interfaces
Chengyun Hua, Xiangwen Chen, Navaneetha K. Ravichandran +1
Interfaces play an essential role in phonon-mediated heat conduction in solids, impacting applications ranging from thermoelectric waste heat recovery to heat dissipation in electr…
Crystalline Polymers with Exceptionally Low Thermal Conductivity Studied using Molecular Dynamics
Andrew B. Robbins, Austin J. Minnich
Semi-crystalline polymers have been shown to have greatly increased thermal conductivity compared to amorphous bulk polymers due to effective heat conduction along the covalent bon…
Temperature Dependent Mean Free Path Spectra of Thermal Phonons Along the c-axis of Graphite
Hang Zhang, Xiangwen Chen, Young-Dahl Jho +1
Heat conduction in graphite has been studied for decades because of its exceptionally large thermal anisotropy. While the bulk thermal conductivities along the in-plane and cross-p…
Thermal phonon boundary scattering in anisotropic thin films
Austin J. Minnich
Boundary scattering of thermal phonons in thin solid films is typically analyzed using Fuchs-Sondheimer theory, which provides a simple equation to calculate the reduction of therm…
Multidimensional quasiballistic thermal transport in transient grating spectroscopy
Austin J. Minnich
Transient grating spectroscopy has emerged as a useful technique to study thermal phonon transport because of its ability to perform thermal measurements over length scales compara…
Active Thermal Extraction of Near-field Thermal Radiation
Ding Ding, Austin J. Minnich
Radiative heat transport between materials supporting surface-phonon polaritons is greatly enhanced when the materials are placed at sub-wavelength separation as a result of the co…
