Abstract :
A lateral diamond field emitter was fabricated by a diamond patterning technique that utilized an oxide patterning and lift-off process on a silicon-on-insulator (SOI) wafer. An anode-cathode spacing of 2 μm between the diamond anode and cathode was achieved. The fabricated lateral emitter diode exhibits excellent emission characteristics with a low turn-on voltage of 5 V and a high emission current of 6 μA from 4 diamond fingers at anode voltage of 25 V. The low turn-on voltage represents one of the best reported lateral field emitter structures. The lateral diamond field emitter is a promising candidate for vacuum microelectronic applications
