## Description

- description: Carbon nanotubes are uniquely featured by the nanoscale tubular structure
    with a highly-curved surface and defined chirality. The diameter and chirality
    fundamentally determine their stability, electrical and thermal properties. Up
    to now, the relationship between the intrinsic thermal conductivity and the atomic
    features of CNTs has not been established, due to the challenges in precise measurements
    and characterizations. In this work, we develop a micro electro-thermal device
    enabling simultaneous thermal measurements by Raman spectroscopy and atomic structural
    characterization by transmission electron microscopy for individual CNTs. The
    influence of diameter and chirality is systematically investigated. In addition,
    the temperature dependence of the thermal conductivity was extracted from parameter
    optimization of finite-element modeling. It is found that the thermal transport
    of CNTs depends mainly on the diameter, while the chiral angle has no significant
    influence. Along with increasing diameter, the room temperature thermal conductivity
    increases and eventually approaches the limit of flat graphene.
