Direct prediction of phonon density of states with Euclidean neural networks
Zhantao Chen, Nina Andrejevic, Tess Smidt +6
Machine learning has demonstrated great power in materials design, discovery, and property prediction. However, despite the success of machine learning in predicting discrete prope…
Quantized Thermoelectric Hall Effect Induces Giant Power Factor in a Topological Semimetal
Fei Han, Nina Andrejevic, Thanh Nguyen +14
Thermoelectrics are promising by directly generating electricity from waste heat. However, (sub-)room-temperature thermoelectrics have been a long-standing challenge due to vanishi…
Observation of second sound in graphite at temperatures above 100 K
Samuel Huberman, Ryan A. Duncan, Ke Chen +6
Wavelike thermal transport in solids, referred to as second sound, has until now been an exotic phenomenon limited to a handful of materials at low temperatures. This has restricte…
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…
Simultaneously high electron and hole mobilities in cubic boron-V compounds: BP, BAs and BSb
Te-Huan Liu, Bai Song, Laureen Meroueh +5
Through first-principles calculations, the phonon-limited transport properties of cubic boron-V compounds (BP, BAs and BSb) are studied. We find that the high optical phonon freque…
Efficiency Limits of Solar Energy Harvesting via Internal Photoemission in Carbon Materials
Svetlana V. Boriskina, Jiawei Zhou, Zhiwei Ding +1
We describe strategies to estimate the upper limits of the efficiency of photon energy harvesting via hot electron extraction from gapless absorbers. Gapless materials such as nobl…
Phonon Hydrodynamic Heat Conduction and Knudsen Minimum in Graphite
Zhiwei Ding, Jiawei Zhou, Bai Song +4
In the hydrodynamic regime, phonons drift with a nonzero collective velocity under a temperature gradient, reminiscent of viscous gas and fluid flow. The study of hydrodynamic phon…
Green's Functions of the Boltzmann Transport Equation with the Full Scattering Matrix for Phonon Nanoscale Transport beyond the Relaxation Time Approximation
Vazrik Chiloyan, Samuel Huberman, Zhiwei Ding +4
The phonon Boltzmann transport equation (BTE) has been widely utilized to study thermal transport in solids. While for a number of materials the exact solution to the BTE has been…
study of electron mean free paths and thermoelectric properties of lead telluride
Qichen Song, Te-Huan Liu, Jiawei Zhou +2
Last few years have witnessed significant enhancement of thermoelectric figure of merit of lead telluride (PbTe) via nanostructuring. Despite the experimental progress, current und…
Constructing and proving the ground state of a generalized Ising model by the cluster tree optimization algorithm
Wenxuan Huang, Daniil Kitchaev, Stephen Dacek +3
Generalized Ising models, also known as cluster expansions, are an important tool in many areas of condensed-matter physics and materials science, as they are often used in the stu…
The Non-Perturbative Quantum Nature of the Dislocation-Phonon Interaction
Mingda Li, Zhiwei Ding, Qingping Meng +5
Despite the long history of dislocation-phonon interaction studies, there are many problems that have not been fully resolved during this development. These include an incompatibil…
