The thermal properties of nanoscale materials are of fundamental interest and also play a critical role in controlling the performance and stability of nanodevices made of these materials. However, the measurements of thermal properties of nanomaterials at a mesoscopic scale have been technically challenging problems. We have fabricated submicron scale devices hybrided with nanoscale materials using state-of-art microfabrication thechniques. The thermal conductivity and thermoelectric power of carbon nanotubes and other nanowires have been measured at mesoscopic levels and exhibit distinticvely different behaviors from bulk material measurement.
