Abstract

The thermal properties of Ge nanowires, SnO2 nanobelts and single wall (SW) carbon nanotubes (CNT) were measured in the temperature range of 4.2 to 400 K. The microdevice used for measuring consisted of two SiN x membranes each suspended by five 400-μm-long SiNx beams. To grow SWCNT's bridging the two membranes chemical vapor deposition (CVD) method was employed. The results show that due to the unique crystalline structure, boundary scattering is nearly absent in CNT's, giving rise to super high thermal and electrical conductivity.
