We investigated Carbon Buckypaper with respect to field emission properties, especially long-term field emission stability and under well-defined stress conditions. The Carbon Buckypaper field emitters showed a threshold field strength of about 1Vμm -1 for an emission current of 1nA. Field emission current densities of more than 10mAcm -2 are measured for higher applied field...
A novel process for growth of carbon nanotubes using plasma processes is reported. This process consists of formation of nanotips on substrate and growth of carbon nanotubes on it. The formation of the nanotips, which were formed under an intention to control formation of catalyst nanoparticles, was carried out on substrates by reactive ion etching. After the nanotips formation, the carbon nanotubes...
Plasma enhanced chemical vapor deposition (PECVD), which enables growth of vertically aligned carbon nanotubes (CNTs) directly onto a solid substrate, is considered to be a suitable method for preparing CNTs for nanoelectronics applications such as electron sources for field emission displays (FEDs). For these purposes, establishment of an efficient CNT growth process has been required. We have examined...
