A　direct　current　(DC)　electrophoresis　deposition　method　(EPD)　was　used　for　preparing　Tetrapod-like　ZnO　film　cathode　on　stable　and　electrically　conducting　metal　mesh　substrates.　Field-emission　measurement　reveals　that　the　tetrapod-like　ZnO　film　deposition　on　metal　mesh　posses　a　good　emission　property　with　very　low　turn-on　electric　fields　of　1.95V/μm　and　low　threshold　field　of　∼3.8V/μm　(for　current　density　of　1mA/cm2).　Furthermore,　large　emission　current　densities　of　2.2　mA/cm2　were　obtained　at　reasonably　low　fields　of　less　than　∼4.9　V/μm.　These　enhanced　emission　properties　are　attributed　to　the　high-conductivity,　stable　nature　of　the　mesh　substrate　onto　which　the　Ag　paste　films　are　attached　and　weaker　field-screening　effect.　©　2010　IEEE.
