Thermal Contact Resistance and Thermal Conductivity of a Carbon Nanofiber Conference Paper uri icon

abstract

  • We have used a microfabricated device to measure the thermal contact resistance between a 152-nm-diameter carbon nanofiber and the measurement device, and found that heat conduction models based on Fourier's law can underestimate the thermal contact resistance at the nanoscale constriction if a large reduction in the effective thermal conductivity of the constriction is not taken into account. With the thermal contact resistance reduced by the deposition of a platinum layer on the contact, we observed that the thermal conductivity of the carbon nanofiber grown by using a plasma enhanced chemical vapor deposition method is comparable to that of graphite fibers grown by pyrolysis of natural gas prior to high-temperature heat treatment.
