Stable Field Emission Property of Patterned MgO Coated Carbon Nanotube Arrays

Due to the high field enhancement factor and photon-absorption efficiency, carbon nanotubes (CNTs) have been widely used in optically induced field-emission as a cathode. Here, we report vertical carbon nanotube arrays (VCNTAs) that performed as high-density electron sources. A combination of high applied electric field and laser illumination made it possible to modulate the emission with laser pulses. When the bias electric field and laser power density increased, the emission process is sensitive to a power law of the laser intensity, which supports the emission mechanism of optically induced field emission followed by over-the-barrier emission. Furthermore, we determine a polarization dependence that exhibits a cosine behavior, which verifies the high possibility of optically induced field emission.

Cathode Electrode

With high effective screen-printing process, the field emission display panel with double stripe emitters was fabricated and their good field emission property was also characterized. Using sintered silver slurry with better electric conduction property as material, the cathode electrode including two parts was formed. The top cathode electrode was made up of two silver stripes, which the carbon nanotube material would reside on its surface. The bottom cathode electrode was separated by the cathode separate layer with the top cathode electrode, but the electric-connection would be performed between them through the preformed round holes. Using carbon nanotube as cathode, the field emission display panel with double stripe emitters was demonstrated.
