The　field　emissin　properties　of　tetrapod-liked　zinc　oxide　nanoneedles　(T-ZnO)　on　silver　electrodes　were　enhanced　by　coating　with　graphene　oxide　(GO)　sheets.　Field　emission　device　based　on　GO　sheets　coated　T-ZnO　exhibited　lower　operation　voltage,　better　stability　and　more　emission　uniformity　when　compared　with　the　pure　T-ZnO　emitters.　It　is　proposed　that　the　introduction　of　GO　sheets　improved　the　mechanical　connection　and　electrical　conduction　between　the　T-ZnO　and　Ag　electrode,　and　resulted　in　the　improved　field　emission　property　for　the　emitters.　©　2012　Bentham　Science　Publishers.
