Achieving Minimal Heat Conductivity by Ballistic Confinement in Phononic Metalattices
Weinan Chen, Disha Talreja, Devon Eichfeld +14
Controlling the thermal conductivity of semiconductors is of practical interest in optimizing the performance of thermoelectric and phononic devices. The insertion of inclusions of…
Phonon Quantum Phase Transition
Ricardo Pablo-Pedro, Nina Andrejevic, Yoichiro Tsurimaki +5
We show that a quantum phase transition can occur in a phonon system in the presence of dislocations. Due to the competing nature between the topological protection of the dislocat…
Theory of Electron-Phonon-Dislon Interacting System - Toward a Quantized Theory of Dislocations
Mingda Li, Yoichiro Tsurimaki, Qingping Meng +4
We provide a comprehensive theoretical framework to study how crystal dislocations influence the functional properties of materials, based on the idea of quantized dislocation, nam…
Lattice dynamics model calculation of Kapitza conductance at solid-fluid interfaces
Sanghamitra Neogi, Gerald D. Mahan
Existing theoretical models of the interfacial thermal conductance, i.e., Kapitza conductance, of insulating solid-fluid interfaces only consider bulk properties, e.g., acoustic mi…
Umklapp Scattering and Heat Conductivity of Superlattices
M. V. Simkin, G. D. Mahan
The mean free path of phonons in superlattices is estimated. It is shown to be strongly dependent on the superlattice period due to the Umklapp scattering in subbands. It first fal…
Diffusion and Transport Coefficients in Synthetic Opals
J. O. Sofo, G. D. Mahan
Opals are structures composed of the closed packing of spheres in the size range of nano-to-micro meter. They are sintered to create small necks at the points of contact. We have s…
