The growing mechanism of the CNT and the correlation between the diameters of the CNT to the particle size of the catalyst and the effect of an Al buffer layer between the active catalyst material Ni on the growth of CNT using PECVD had been studied. Using a thin layer of Al as a buffer layer between active catalyst material does produce a higher density of catalyst particles as compared to the one...
A carbon nanotube (CNT) growth process on HfO2 is reported for the first time for application in nano-sensors. The process uses a combination of Ge nanoparticles and ferric nitrate dispersion and achieves an increase in CNT density from 0.15 to 6.2 mum length/mum2 compared with the use of ferric nitrate dispersion alone. The growth process is validated by the fabrication of back-gate CNT field-effect...
