Temperature Distribution and Thermal Conductivity Measurements of Chirality-Assigned Single-Walled Carbon Nanotubes by Photoluminescence Imaging Spectroscopy.

ABSTRACT: It is expected that single-walled carbon nanotubes (SWCNTs) have high thermal conductivity along the tube axis and that the thermal conductivities depend on their structure, such as length, diameter, chirality (n, m), and so forth. Although many experimental measurements of the thermal conductivity have been reported, the SWCNT structure was not characterized sufficiently. In particular, the chirality was not assigned, and it was not confirmed whether SWCNT was isolated or not (bundled with multiplicate SWCNTs). Therefore, measured values widely vary (10¹ to 10⁴ W/(m·K)) so far. Here, we measured the thermal conductivity of chirality-assigned SWCNTs, which were individually suspended, by using photoluminescence (PL) imaging spectroscopy. The temperature
