Abstract

The field emission characteristics from the SiC micro powders with sharp edge are investigated. The edge of the SiC powder works as the field emitter. The emission current follows the Fowler-Nordheim relationship. An excellent emission stability in short term is confirmed. These results show that the SiC powder is a good candidate for field electron source.

碳化硅微粉的场发射特性
研究了具有锋利边缘的碳化硅微粉的场发射特性。SiC粉末的边缘作为场发射极。发射电流遵循Fowler-Nordheim关系。在短期内具有良好的发射稳定性。这些结果表明,SiC粉末是一种很好的场电子源。
