| Research Abstract |
Toward the realization of next-generation nanodevices, the Joule heating and heat transport in nanomaterials are one of the high-priority issues. In this project, we have theoretically investigated the heat transport in carbon nanotubes, which are promising candidates for heat removal materials. The remarkable results of this project are (i)Reduction of thermal conductivity due to defects and impurities scattering, (ii)Bending robustness of thermal conductance, (iii)Quasi-ballistic transport in micrometer-length nanotubes, and (iv)Development of novel simulation technique for heat transport in sub-millimeter nanotubes.
