Unique Heat Conduction Properties of Graphene – From Fancy Physics of Phonon Transport to Applications in Thermal Management Seminar by Professor Alexander Balandin

ABSTRACT:  The discovery of unique thermal properties of graphene stimulated experimental, theoretical and computational research directed at understanding phonon transport and thermal conduction in two-dimensional material systems [1-3]. In the first part of the talk, I will review the history and recent results in the graphene thermal field, indicating open physics questions, and providing comparison of different experimental and computational approaches. The extremely high thermal conductivity of graphene, its mechanical flexibility and low cost of the liquid-phase-exfoliated graphene have also led to an explosive growth in research focused on thermal management applications of graphene. In the second part of the talk, I will review results pertinent to graphene’s use as fillers in various thermal interface materials. Specifically, I will address the issue of thermal percolation in graphene composites and resent results for graphene-enhanced thermal interface materials and coatings, which meets industry’s requirements for thermal management of advanced electronics [3-4].
