Abstract：

Using　Zn　powder　as　the　raw　material,　Tetrapod-like　ZnO　nanoneedles　with　controllable　morphology　and　size　were　successfully　prepared　by　chemical　vapor　deposition.　A　screen　printed　normal-gated　triode　with　Tetrapod-like　ZnO　nanoneedles　field　emitters　is　demonstrated.　Field　emission　measurements　show　that　the　Tetrapod-like　ZnO　nanoneedles　FED　triode　devices　posses　a　good　field　emission　property.　The　turn-on　voltage　is　270V.　An　anode　current　of　2.75　mA　and　a　gate　current　of　0.43　mA　are　extracted　at　a　gate　voltage　of　600　V　with　a　brightness　of　2300　cd/m(2).
