2019 MRS Spring Meeting & Exhibit

Symposium QN05-Emerging Thermal Materials—From Nanoscale to Multiscale Thermal Transport, Energy Conversion, Storage and Thermal Management

Thermal properties of materials, such as conductivity, transduction and expansion, often determine or limit material functionality (~nanoscale) and device design (~micro- to macroscale). Thus, a broad expanse of research is currently engaged in synthesis and characterization of novel thermal materials, as well as theoretical efforts to understand thermal properties and predict thermal materials and functionalities. This symposium will broadly cover thermal properties of current and emerging thermal materials, with aspects bridging nanoscale and multiscale thermal transport to applications. It will highlight three emerging aspects of thermal energy research: (i) new thermal materials and functionalities, (ii) novel theories and characterization techniques, and (iii) emerging applications and devices. The first part of the symposium will focus on emerging materials and systems for thermoelectric, thermophotovoltaics, thermo-electrochemical, thermo-acoustic, ferroelectric, and magnetic energy harvesting, storage, and materials with extreme thermal conductivity for thermal management. Discussions include rational design, chemical synthesis, growth mechanisms, fabrication routes, property optimization and external field control, all including new fundamental science breakthroughs. The second part of this symposium will focus on recent developments in nanoscale thermal transport as characterized and described by new experimental metrologies and theoretical methods. With continuing device miniaturization, as well as the development of novel measurement techniques, such as ultrafast laser spectroscopies, that make possible the probing of material properties at these length scales, new insights of non-Fourier heat conduction and near-field radiation being uncovered. Discussions will include recent measurements near nanoscale resolution using advanced characterization techniques such as pump-probe thermoreflectance measurements, Raman thermometry, atomic force microscopy-based thermometry, and recent modeling using atomistic tools such as density functional theory, molecular dynamics, and Green's functions methods, as well as multi-scale modeling. Possible topics of interest are thermal transport in extreme environments (high pressure/temperature), phase change materials for energy storage, non-Fourier thermal transport and conductance via other than phonon and electron heat carriers, thermal radiation from metamaterials, nanothermodynamics. The third part of the symposium will focus on devices and applications over multiple length scales: examples include but are not limited to nanoscale thermal rectification devices, mesoscopic phononic crystals, and macroscopic thermal batteries, solar thermal plants and data farms, as well as energy conversion, storage, and thermal management of electronics, photonics, and batteries.
