Mode- and Space- Resolved Thermal Transport of Alloy Nanostructures
S. Aria Hosseini, Sarah Khanniche, G. Jeffrey Snyder +3
Nanostructured semiconducting alloys obtain ultra-low thermal conductivity as a result of the scattering of phonons with a wide range of mean-free-paths (MFPs). In these materials,…
Enhanced Thermoelectric ZT in the Tails of the Fermi Distribution via Electron Filtering by Nanoinclusions -- Model Electron Transport in Nanocomposites
S. Aria Hosseini, Devin Coleman, Sabah Bux +2
Silicon carbide nanoparticles with diameters around 8 nm and with narrow size distribution have been finely mixed with doped silicon nanopowders and sintered into bulk samples to i…
Universal Effective Medium Theory to Predict the Thermal Conductivity in Nanostructured Materials
S. Aria Hosseini, Sarah Khanniche, P. Alex Greaney +1
Nanostructured materials enable high thermal transport tunability, holding promises for thermal management and heat harvesting applications. Predicting the effect that nanostructur…
Enhanced Thermoelectric Performance of Polycrystalline Si0.8Ge0.2 Alloys through the Addition of Nanoscale Porosity
Hosseini, S. Aria, Romano +3
Engineering materials to include nanoscale porosity or other nanoscale structures has become a well-established strategy for enhancing the thermoelectric performance of dielectrics…
Heat current anticorrelation effects leading to thermal conductivity reduction in nanoporous Si
Laura de Sousa Oliveira, S. Aria Hosseini, Alex Greaney +1
Prevailing nanostructuring strategies focus on increasing phonon scattering and reducing the mean-free-path of phonons across the spectrum. In nanoporous Si materials, for example,…
Mitigating the Effect of Nanoscale Porosity on Thermoelectric Power Factor of Si
S. Aria Hosseini, Giuseppe Romano, P. Alex Greaney
The addition of porosity to thermoelectric materials can significantly increase the figure of merit, ZT, by reducing the thermal conductivity. Unfortunately, porosity is also detri…
