Figure 3. Thermal emission spectra and temperature of a CNT.

(a) Thermal emission spectra of the same CNT as that shown in Fig. 2a with Vbias ranging from 2.93 to 3.21 V at 0.04 V intervals. The solid lines are the fitting of experimental spectra according to Planck's law. (b) T-Vbias and P-Vbias plots of the CNT.
