چکیده
|
Cu/zno nanostructures have been synthesized by cathodic electrodeposition technique. the field emission characteristicsof the as-synthesized films, obtained by planar diode configuration, showed high emission current andstable field emission over long hours of operation. the analysis of the field emission characteristics, based on variationof the fowler-noedheim plots parameters and sem images, suggests an emission evolution during operationtime. the evolution of the field emission is explained on the basis of the field induced diffusion/activation of the cunanoparticles.
