Field emission (FE) properties of individual single-walled carbon nanotubes (SWCNT) were investigated inside a field emission-scanning electron microscopy. The individual SWCNT turned on a voltage of 23V defined to produce a current of 10pA, and was saturated at around 43V and 880nA. The FE characteristic of individual SWCNT also followed a conventional Fowler–Nordheim (F–N) theory in which a single...
The aim of this work was to study the relationship between parameters of the electron field emission and the film deposition method. In this study two methods were applied: classical radio frequency plasma-assisted chemical vapor deposition (RF PACVD) to produce diamond-like carbon (DLC) layers and chemical vapor deposition (CVD) to produce carbon nanotubes (CNT). DLC layers were grown on n-type silicon...
Zinc oxide (ZnO) nanostructures were grown on vertically aligned carbon nanotubes (CNTs) using thermal chemical vapor deposition (CVD) to enhance the field emission characteristics. The shape of ZnO nanostructure was tapered. Scanning electron microscopy (SEM) image showed the ZnO nanostructures were grown onto CNT surface uniformly. The field electron emission of pristine CNTs and ZnO-coated CNTs...
The patterned electron field emission of printed carbon nanotube (PCNT) films using image transfer technology is reported. If we transfer an image to the surface of PCNT films, such as using a stamp, the emission image of PCNT films will be the transferred pattern. Based on many experiments, we are convinced that the essential feature of pattern emission from PCNT films by image transfer technology...
