抄録

Carbon nanotubes (CNTs) have high intrinsic thermal conductivity and high surface-to-volume ratio, thus CNT-based fins is considered to be promising for hign performance device cooling. In addition, exploring the heat transfer between a CNT and gases is important not only for CNT-based gas sensors but also for scientific interest oi mterfacial heat transport. In this work, we have developed novel technique for measuring heat transfer coefficients between an individual carbon nanotube and surrounding gases (Air, N_2, Ar, He) using platinum hot film sensor. Measured heat transfer coefficients quantitatively show good agreement with estimated values by kinetic gas theory at atmospheric pressure but do not match with theoretical prediction at low pressure regime.
