Large Field Emission Current from Carbon Nanotube Emitter Arrays Growth on Cobalt Film

In this paper, vertically aligned carbon nanotube (CNT) emitters on nickel film were synthesized by microwave plasma chemical vapor deposition for large current field emission applications. The as-grown CNT arrays were characterized using scanning electron microscopy (SEM). Also the field emission current density against applied voltage and the F-N plot of plasma etched CNTs were measured
