(a) SEM image of carbon nanotubes suspended over a trench. (b) band Raman frequency measured along the length of the nanotube in (a) at different laser powers. (c) Laser heating profile of the suspended nanotube shown in Fig. 1(a). Error bars reflect the uncertainties in the band shift and its temperature coefficient.
Temperature increase profile along a suspended nanotube, as determined from the band downshifts measured with and laser power. Error bars are as in Fig. 1.
Summary of the temperature rise profile measurements of four suspended nanotubes.
