&nbsp;&nbsp;A novel method to make the sharp emitter tips having low threshold voltage of field emission was achieved using nanodiamond particles on conductive amorphous carbon films. A conductive tetrahedral amorphous (ta) carbon film and nano-sized diamond particles with the size of 50 to 200 nm were sequentially deposited by cathordic arc method using a glass substrate at room temperature. Tip structure with the height of 10 to 40 nm was formed by H<sub>2</sub> plasma etching of the diamond particles/ta-C double layer film. The threshold voltage of the field emission from the tip structures formed by the H<sub>2</sub> plasma etching was 3 V/&mu;m that was significantly lower than 10.4 V/&mu;m for the as-deposited diamond particles/ta-C double layer carbon film. This selective dry etching method using the nano-diamond particles could fabricate sharp and high density nano-sized diamond emitters on conductive ta-C films without any photo-masks of lithography processes.<br>
