We have developed a technique for fabrication of a field emitter array (FEA) of carbon nanotubes (CNTs) to obtain a high emission current along with a high current density.

These studies indicate that we can use the hybrid nanostructure to improve conductivity and contact resistance, which results in enhancement of the FE propertiesДЄ fabrication method for field emitter array of carbon nanotubes with improved carbon nanotube rootingД¬houhan, V., E-mail: [School of High Energy Accelerator, The Graduate University for Advanced Studies, Tsukuba 305-0801 (Japan) Noguchi, T. For further enhancement FE of hybrids, Ag Nanoparticles (NPs) were decorated on the hybrids and FE characteristics were also studied. The better FE properties result from the improved electrical properties. The low turn-on electric field (EF), the low threshold EF and the reliability FE properties are obtained from the hybrid emitter.

The field emission (FE) performance of the hybrid emitter is greatly improved compared with that of only GP or MCNTs emitter. The graphene (GP) and multi-walled carbon nanotubes (MCNTs) hybrid nanostructure emitter was constructed by a larger scale electrophoretic deposition (EPD) method.

Therefore, it is of great interest to present a state of art study on the complete solution of FN equation for CNTs based field emitter displays. With the help of modified FN equation, an important formula for effective emitting area (active area for emission of electrons) has been derived and employed to calculate the active emitting area for CNT field emitters. The work function of nanostructure by using FN plot has been calculated with reverse engineering.

High aspect ratio of CNTs leads to large field enhancement factor and lower operating voltages because the electric field strength in the vicinity of the nanotubes tip can be enhanced by thousand times. In this work, an effort has been made to present the field emission mechanism in carbon nanotubes (CNTs) which have tip type geometry at nanoscale.
