Abstract :
The edges and corners of nanocrystalline diamond were natural field-emitters. Nano-graphite was mixed in nanocrystalline diamond and cellulose or other organic vehicles to fabricate paste for screen-printed film. The aim of mixed nano-graphite to enhance electric conduction of Nano-diamond film. Through enough ultrasonic disperse the nano-diamond, the paste was screen-printed on the substrates to form Nano-diamond film (NDF). The sintering process and post-treatment of Nano-diamond film were tested. SEM images showed that the surface morphology of NDF was improved, and the nano-diamond emitters were exposed from NDF through the special thermal-sintering technique and post-treatment process. The field-emission characteristics of Nano-diamond film were tested and analyzed. Finally, a pressure sensor based on field-emission of Nano-diamond film was designed. Result of MATLAB simulation indicated that the change curve of dJ/dS with dF/dS was linear.
