摘要: Recent development of diamond field emitter cathodes and devices fabricated from molding process is presented. Practical modifications involving the sp2 content, surface treatment, boron doping, tip sharpening to further enhance emission are discussed. A new fabrication for achieving ultrasharp tips with a radius curvature less than 5 nm has been achieved shows significant improvement in characteristics. Discussion this enhanced microtips presented accordance analysis behavior. The high site density uniform microtip arrays We also report technique fabricate self-aligned gate diodes, which achieve very characteristics at extremely low applied voltage. latest aims integrate emitters silicon-based MEMS processing technology totally monolithic devi...
