Carbon Nanotube Electron Sources: From Electron Beams to Energy Conversion and Optophononics
Figure 8
Laser-induced localized heating of the side of a carbon nanotube forest through the Heat Trap effect: (a) schematic of the experimental apparatus; (b) device diagram showing the focused nature of the illumination. Note that the illuminated spot size is significantly smaller than the lateral dimensions of the carbon nanotube forest, which are on the order of millimeters; (c) photo of the nanotube forest (highlighted by the dashed box) showing the incandescence glow from the locally heated spot. The photo was taken while a filter in front of the camera blocked the laser light, so that only the incandescence of the hot spot is seen (reprinted from [188].
