(Color online) Schematic diagram of the two-laser measurement setup.
(Color online) (a) SEM image of a 76 μm long suspended CNT. (b) Temperature profiles measured along the CNT in vacuum under different electrical heating powers. The TEM image of the measured CNT is shown in the inset of (a). The scale bar is 50 nm.
(Color online) (a) Temperature profiles along a 44 μm suspended CNT measured in vacuum. Each symbol represents a different location of the 532 nm focused laser heat source. (b) Comparison of the normalized temperature profiles measured in vacuum and in air.
(Color online) Normalized temperature profile along a suspended CNT measured using the two-laser measurement technique. The solid red curve shows the exponential fit to the normalized temperature profiles starting from x = ±0.375 μm.
