Carbon Nanotube Electron Sources: From Electron Beams to Energy Conversion and Optophononics

Figure 10

The temperature of an illuminated spot as a function of the intensity of incident light for a carbon nanotube forest and a regular isotropic bulk conductor; the intensity required for significant heating in the nanotube forest is over three orders of magnitude smaller than that in the bulk. This is due to the Heat Trap mechanism (reprinted from [194] with modifications).
