Abstract：

A　simple　CNT/Fe3O4　composite　electrophoretic　deposition　method　to　improve　the　field　emission　cathode　properties　of　carbon　nanotubes　(CNTs)　is　proposed.　It　is　found　that　CNT/Fe3O4　composite　electrophoretic　deposition　leads　to　better　field　emission　performance　than　that　of　single　CNT　electrophoretic　deposition.　The　result　is　investigated　using　SEM,　J-E　and　FE.　After　the　process,　the　turn-on　electric　field　decreases　from　0.882　to　0.500　V/μm　at　an　emission　current　density　of　0.1　mA/cm　2,　and　the　latter　increases　from　0.003　to　1.137　mA/cm2　at　an　electric　field　of　0.64　V/μm.　CNT/Fe3O4　composite　electrophoretic　deposition　is　an　easy　and　effective　cathode　preparation　for　field　emission　display　applications.　©　2011　Chinese　Institute　of　Electronics.
