Los Angeles, CA 90095 This study reports the experimental measurements and theoretical calculations of phonon transport in the record-high thermoelectric material, i.e. Our finding underscores the promise of boron phosphide as a high thermal conductivity material for thermal management and provides a microscopic-level understanding of the phonon spectra and thermal transport mechanisms of boron phosphide, to enable a rational design of high thermal conductivity materials and nano- to multiscale devices. General Inquiries: oissassi@saonet.ucla.edu, Research & Assessment at the Dashew Center. We find an ultrahigh room-temperature thermal conductivity through strong carbon-carbon bonding up to 2100 W/mK beyond most common materials and the recently discovered boron arsenide. Furthermore, we performed ab initio calculations using different methods: in comparison with self-consistent phonon theory, the harmonic and quasi-harmonic models that have been widely used in current phonon calculations, fail to accurately predict these important thermophysical properties. Dr. The h Index for Computer Science by Jens Palsberg In this paper, J. E.

We acknowledge that these killings cause particular pain for Black mathematicians and students, … Here, we demonstrated a flexible thermoelectric copper selenide (Cu2Se) thin film through a low-cost and scalable spin coating process for waste heat harvesting applicatons. Despite high density of vacancy impurities, our measurement shows a reasonable high thermal conductivity, as an important first step towards developing high-conducting materails. January 26, 2021, Huan and Hang's paper on ultrahigh thermal conductivity was accepted for publication. Experimental measurement is compared with modeling resutls based on transient frequency-dependent Boltzmann transport equation and multi-scale Monte Carlo methods, which enables us to better understand heat transfer and design energy materials. Using new materials, modeling design, and self-assembled manufacturing, we report high performance thermal management with excellent elastic compliance similar to that of soft biological tissues down to 100 kPa, high flexibility, and preserves over at least 500 bending cycles a high thermal conductivity over about 100 times improvement of a typical polymer.
