| 中文摘要 | Field electron emission of nanocrystalline diamond films with controllable grain size and graphite content, grown by microwave plasma-assisted chemical vapor deposition using N(2)/CH(4)/H(2) as precursors, is studied. A bistable current-voltage characteristic is found. Current jumps ("steps") are observed when a point probe of Mo is used as the anode. However, when the point probe is replaced by a large quartz plate coated with indium-tin-oxide (ITO), emission domains, which consist of many lighting spots, appear on the ITO plate. Bistable behavior may be understood in terms of the negative differential conductance induced instability. Current jumps can be attributed to the generation and elimination of conducting channels. It is suggested that the electron emission from individual diamond nanocrystallites is a switching process. It is noticed that, when the microstructure of the films is uniform enough, the micro-scale switching behavior can even be amplified to macroscale. (C) 2001 American Institute of Physics. |
