Emission property of composite micro tubule cathode molded by capillary action
A conductive polymer composite was used in fabrication of field emission (FE) electrode array. The FE electrode was prepared by using a template: polycarbonate membrane filter of 0.4 similar to 1.2 mu m diameter pores. Initially, the conductive polymer was spin-coated on the ITO glass. Polymer tubules were molded by capillary action of the polymer solution into the template. After removing the template, metal were deposited by sputtering or electroplating onto the polymer to enhance the field emission. The micro structure was then observed by using SEM and analyzed via EDAX step by step along the fabrication procedure. This structure showed that FE started at 0.6V/mu m under vacuum condition of 10 similar to 6 Torr.
