Abstract: Thermal transport at carbon nanotube (CNT) interfaces was investigated by characterizing the
interfacial thermal conductance between metallic- or semiconducting-CNTs and three different
surfactants. We thereby resolved a difference between metallic- and semiconducting-CNTs. After
slightly heating the CNTs dispersed in a suspension, we obtained cooling curves by monitoring the
transient changes in absorption, and from these cooling curves, we extracted the interfacial thermal
conductance by conducting thermal model analysis. We found that the semiconducting-CNTs
unexpectedly exhibited a higher conductance of 11.5 MW/m2
