Symposium NM08-Nanoscale Heat Transport—Fundamentals

Understanding and controlling the interactions between energy carrying particles and nanostructural features brings new opportunities for manipulation of thermal transport processes and thermal physical properties. Due to the continuous progress in nanofabrication technologies, modern nanoscale materials and devices have characteristic length scales of the order of relevant energy carriers such as phonons, phonons, electrons, and magnons. This translates into an unprecedented opportunity to achieve novel thermal properties and functions. Despite significant advances, a better understanding of thermal transport in nanoscale materials and interactions between energy carriers and surfaces and interfaces is still required. There exist multiple thermal transport regimes that need to be fully elucidated in order to obtain a full spectrum of thermal capabilities: these include ballistic, quasi-ballistic, localized, hydrodynamic, coherent, incoherent, strongly anharmonic regimes. In addition to the complexities of crystalline materials, materials and systems with disordered or amorphous structures also possess significant challenges for understanding and manipulating thermal transport processes. In bulk crystalline systems, manipulation of crystal bonding and distorted local/global structures such as lone pairs, grain boundaries etc. also allow for manipulation of phonon mean free paths down to atomic length scales. In addition, new tools such as machine learning and high-throughput experiments can allow for wider exploration of new materials and development of new experimental techniques. This symposium will bring together a wide range of different thermal transport research areas including experimental, theoretical, and computational techniques recently developed to address the unknowns on nanoscale thermal transport phenomena with the objective of obtaining a better basic understanding of thermal transport processes in technologically relevant materials and devices.

Topics will include:

Theory and experiments on nanoscale heat transport phenomena
Thermal conductance at interfaces
Heat conduction in disordered and amorphous materials
Ultralow thermal conductivity in crystalline bulk thermoelectric materials
Thermal radiation at the nanoscale
Machine learning to predict and understand thermal properties of materials
Non-equilibrium and picosecond thermal transient behaviors
Heat transport in soft matter (e.g. biological and bioinspired materials)
Thermal phonon imaging
Thermal transport characterization techniques (e.g. mean-free path spectroscopies)
Electron-phonon, and phonon-phonon interactions
Novel models and simulation methods to predict thermal transport properties
