“…22 Small tubes have lower W ad . 23 Since the E kin should be proportional to the growth temperature, the producible type of SWNTs under the low-growth temperature condition can be highly selected compared with that in the higher growth temperature. As we have discussed above, the growth temperature is one of the key parameters to realize the narrowchirality distribution of SWNTs by TP-PCVD.…”

We have realized the direct growth of the short-length (<100 nm) single-walled carbon nanotubes (SWNTs) with a narrow-chirality distribution by time-programmed plasma chemical vapor deposition (TP-PCVD). Transmission electron microscope and atomic force microscope analyses reveal that the very short (<100 nm) SWNTs are selectively grown by precisely controlling their growth time on the order of a few seconds. Direct photoluminescence excitation measurements also show that the chirality distribution of the short SWNTs is fairly narrow, and (7, 6) and (8, 4) dominant short SWNTs are successfully synthesized by TP-PCVD.

“…As the CNT growth process is intimately related to this interface, a thorough investigation of the nature of the interface seems consequential. Owing to the large variety of CNT synthesis, different and (partially) competing growth models exist [15][16][17][18][19][20]. In the most widely used preparation process of chemical vapor deposition (CVD), the choice of transition metal catalyst particles provides a degree of control over the CNT morphology, the production yield, and the growth mode itself (base growth vs. tip growth) [21,22].…”

“…Ab-initio calculations on interfaces between single-wall CNTs and selected metal surfaces reveal the covalent character of the chemical binding and surprisingly high bond strengths [25]. For single-wall CNT growth the adhesion between the catalyst particle and the graphene cap is stated to be the most important point for the cap lift-off [18][19][20]. Koziol et al showed a strong relation between an iron-carbide particle and the radial nanotube layer in MWCNT's grown by CVD process [28].…”

“…Since there is an incubation time difference for each chirality, the number of chirality species grown at the initial growth stage is limited, resulting in the growth of SWNTs with relatively narrow-chirality distributions. However, in order to improve the selectivity of each chirality, it is an important issue to identify the factors which strongly affect the incubation time [8][9][10]. The increase in the incubation time difference (Δt i ) between each chirality is also a significant topic to address.…”

The effect of ion impact on the incubation time of single-walled carbon nanotubes (SWNTs) during plasma chemical vapor deposition (CVD) has been studied. Based on the systematic investigations, the incubation time of large-diameter SWNTs was found to be sensitive to the ion impact during plasma CVD. The incubation time difference (Δt i ) between small-and large-diameter SWNTs can increase up to 120 s with the introduction of appropriate ion impact during the growth process of the SWNTs. The selectivity of the effects of ion impact on the incubation time of small-and large-diameter SWNTs was also found to be sensitive to the hydrogen concentration during plasma CVD. This indicates that the hydrogen ion can play an important role during the nucleation period in the development of SWNTs with plasma CVD. Since the increase in Δt i for each chirality is important for the realization of chirality-selective growth of SWNTs, we believe that our findings can contribute to this aspect, one of the main goals in the science and application fields of SWNTs.
