• W3216971554 abstract "The ability to predict, understand, and control thermal transport in materials and at interfaces remains a critical challenge and goal of nanoscale thermal transport research. In nanostructures where phonons are the primary thermal energy carriers, interfaces between dissimilar materials represent the dominant thermal resistance. An increased understanding of phonon-mediated transport across interfaces is critically needed, so that nanostructured materials can be more effectively designed and implemented. Over the past several decades, the nanoscale heat transfer community has identified and investigated many factors that influence phonon transport across solid–solid interfaces. Experimental data, simulation results and theoretical analysis have all elucidated that vibrational spectra, harmonic and anharmonic processes, defects, mixing, etc., all collectively have an impact on the ability to transport heat across a solid–solid interface. As the community continues to study these phenomena many challenges arise. In the regime of simulations, it is difficult to develop a computational model that captures all the properties of a physical material and the interactions between materials. From the standpoint of the experimentalist, there is no perfect system or set of system that allows factors influencing thermal transport to be decoupled. In all areas of thermal transport research, the challenge is either decoupling or understanding the interplay of complex effects that manifest differently in various materials and experimental/computational environments. At the Nanoscale Energy Transport Laboratory at the University of Virginia, our research efforts combine computational and experimental techniques to model, measure, and predict phonon dynamics, and the resulting thermal properties, for a wide range technologically relevant systems. We have approached this problem experimentally, measuring nanoscale systems with time-domain thermoreflectance (TDTR), and computationally, tracking atomic thermal motion in nonequilibrium molecular dynamics simulations, and investigating quantum mechanical effects using the nonequilibrium Green's functions (NEGF) approach. This work is complicated by the wide spectra of phonon mean free paths, ranging from a single atomic spacing to the size of the material system. Here, we review approaches for measuring, modeling and manipulating thermal boundary conductance across solid–solid interfaces in hopes of developing avenues to control the heat transport at the atomistic length scale. For example, we have demonstrated that introduction of an intermediate layer with average vibrational properties of the two contacts joining at an interface can enhance the interfacial thermal conduction. And by utilizing an exponentially mass-graded interface, we could increase the enhancement, primarily attributed to the strength of anharmonicity. The ultimate goal is to drive the discussion of thermal management from a design afterthought down to the nanoscale where the heat is generated, completing the journey from thermal interface material (TIM) to transistor." @default.
