The　phenomenon　of　electron　emission　from　ferroelectric　cathodes　has　attracted　much　interest　and　today　is　a　subject　of　investigation　all　over　the　world.　In　this　paper,　organic　PVDF　(polyvinylidene　fluoride)　thin　films　were　prepared　by　ultrasonic　atomization　method,　and　pulse　excited　electric　field　induced　electron　emission　from　the　poled　organic　PVDF　ferroelectric　cathode　has　been　investigated.　The　results　indicated　that　the　reason　of　electron　emission　was　the　compensated　charges　on　the　surface　of　organic　ferroelectric　cathode　unbalancing　caused　by　fast　reversal　of　the　polarization.　Repeatable　emissions　were　obtained　from　the　organic　PVDF　ferroelectric　cathode,　which　could　also　be　modulated　at　high　electric　field.　It　is　anticipated　that　an　electron　source,　based　on　emission　from　PVDF　ferroelectric　cathode,　will　comprehensively　trigger　a　novel　type　of　display.
