Development of Nanoscale Thermal Properties Measurement Technique using Near-field Optics (3 report, A Preliminary Measurement using Single-Walled Carbon Nanotube)

摘要

As the nanoscale physics is revealed, it is assumed that particular phenomena such as size effects and ballistic conduction affect the thermophysical properties of materials. Thus, thermophysical properties must be measured in nanoscale in order to be able to adapt them to the nanotechnology industry. However, traditional optical measurement methods lack spatial resolution. We have developed a thermophysical properties measurement technique using near-field optics. It is a noncontact method which has a spatial resolution range possibility of 10～500nm. We conducted preliminary measurements using Single-Walled Carbon Nanotube (SWNT), and successfully produced a result which supports the validity of our measurement technique.
