内容简介 : 

  Nanostructures have a strong impact on thermal transport in materials.  Carbon nanotubes has extremely high thermal conductivity, and has been used as thermal interface materials to enhance heat dissipation of electronic devices. Nanostructures have also been used in liquid cooling to enhance thermal transport, which is an essential component in electronic packaging. On the other hand, nanostructures can reduce thermal transport in materials due to the introduction of extra phonon scattering mechanism. The reduction of thermal conductivity is critical to ensure the efficiency of thermoelectric devices, which is an appealing approach for waste heat recovery by directly converting the heat to electricity. In this talk, I will introduce the approach of using nanostructures to enhance heat transport for thermal management of electronic devices. In the second part, I will talk about using nanostructures to reduce heat transport for thermal energy conversion applications.
