摘要

The thermal boundary resistance between an individual carbon nanotube and a Au surface was measured using a microfabricated hot-film sensor. We used both closed and open-ended multi-walled carbon nanotubes and obtained thermal boundary resistance values of 0.947-1.22 × 10~7KW~(- 1) and 1.43-1.76 × 10~7KW~(- 1), respectively. Considering all uncertainties, including the contact area, the thermal boundary conductances per unit area were calculated to be 8.6 × 10~7-2.2 × 10~8Wm~(- 2)K~(- 1) for c-axis orientation and 4.2 × 10~8-1.2 × 10~9Wm~(- 2)K~(- 1) for the a-axis. The trend in these values agrees with the predicted conductance dependence on the interface orientation of anisotropic carbon-based materials. However, the measured thermal boundary conductances are found to be much larger than the reported results
