Field emission property of micro emitter array fabricated from conducting polymer
Micro scale emitter array was fabricated with a conducting polymer. A simple and easy way of electrochemical template polymerization was utilized in this process. In this study the template membrane was fixed onto an ITO glass electrode by using conductive composite glue. Applying electrochemical potential to the template electrode in monomer electrolyte allowed polymerization of pyrrole within the pores and thus the micro structures were grown. Cyclic voltammetry, SEM and EDAX measurements were done to characterize this emitter array. The emission current measurements were done in 10(-7) Torr condition and results show redox state dependence emission of the polymer electrodes.
