Scholarcy highlights

  • An analytical thermal model is established for the aligned arrays of metallic single-walled carbon nanotubes by pulsed heating
  • A recent approach based on the nanoscale thermocapillary flow enabled the achievement of aligned arrays of highly purified Semiconducting single-walled carbon nanotube by removing the metallic SWNTs in as-grown arrays by direct pulsed current injection
  • Thermal management of this process is critically important since the cumulative heating from the m-SWNT array yields a high temperature increase to cause the difficult control of thermocapillary flow
  • An analytical heat transfer model combining a two-dimensional transient thermal model and a three-dimensional steady state thermal model is established for predicting the temperature increase of the SWNT array under a pulsed current injection with a period step function
  • These results can help guide the purification process to reduce the adverse thermal effects to obtain highly purified Semiconducting single-walled carbon nanotube
