Table 1 Characteristics of the catalyst nanoparticles and the growth of the resultant nanotubes
From: Highly sensitive integrated pressure sensor with horizontally oriented carbon nanotube network
Type of catalyst/CNTs | Formation | Range of size/diameter (nm) | Density (×1010/cm2) | RMS (nm) | Growth rate (μm/min) |
---|---|---|---|---|---|
AuFe catalyst | Connected clusters with small nanoparticles | 16.9 to 200 | 9.07 | 4.81 | - |
MWCNTs | Horizontally oriented | 7.0 to 9.0 | 22.31 | 5.36 | 0.02 |
