PROJECT TITLE :

Enhanced Carbon Nanotube Field Emitter With Adsorbed Au Nanoparticles

ABSTRACT:

Field emission was achieved utilizing vertically aligned carbon nanotubes (CNTs), whose external surface was adorned with Au nanoparticles (NPs). It was found that the average length and diameter of the CNTs were and forty five nm, respectively. Au NPs (around five nm) were coated onto CNT surfaces for field emission. The flip-ON field and current density of the Au-coated CNTs clearly indicate that the Au NPs considerably enhanced field emission. Au NP decoration effectively decreased the work perform and turn-ON field.
