摘要：

Diamond-carbon nanocomposites (DCN) containing diamond and graphitic particles, both a few nanometers in size, were studied as the material for field electron emission. Diamond-carbon mass ratio and grain size were varied to optimize held emission properties. The stable and uniform electron emission was observed at fields E = 10 V mu m(-1) with a negligible hysteresis of I-V curves. Treatment in microwave hydrogen plasma was found to reduce the threshold field for emission owing to preferential etching of carbon component and surface relief sharpening. Ultrathin chemical vapour deposition diamond films can be easily grown on DCN due to the very high nucleation density inherent to this composite. (C) 1999 Elsevier Science S.A. All rights reserved.
