Krypton Gas for High Quality Single Wall Carbon Nanotubes Synthesis by KrF Excimer Laser Ablation

Figure 5

Kataura plot with black points indicating semiconductor nanotubes and red circles indicating metallic nanotubes. The horizontal green line indicates the excitation energy of the green laser (2.33 eV), while the red line indicates the excitation energy of the red laser (1.96 eV). The vertical green lines indicate the diameter distribution of the nanotubes of our ablation product obtained with the green laser and the red line with the red laser (a) and the commercial nanotubes from Sigma obtained with the green laser and the red line with the red laser (b) [33].
