Bolometric Response of a Single-Wall Carbon Nanotube

ORAL

Abstract

We report on the low temperature bolometric (thermal) rf response of individual metallic single-wall carbon nanotubes. This response is used to determine the thermal conductance of the nanotube. Previous work has demonstrated heterodyne mixing in individual carbon nanotubes using either an electrical I-V nonlinearity or a gate-modulated conductance. We distinguish between bolometric mixing and the response due to non-thermal electrical nonlinearities. These experiments are a precursor to proposed terahertz measurements of the frequency-dependent bolometric response of an individual single-wall nanotube.
