    Abstract

    Surface-processed TiC〈110〉 tips have been developed to obtain highly stable emission as a cold field-electron emission source. The surface processing consists of heating the tip at 1000-1100°C in a gas such as ethylene, oxygen or hydrogen sulphide, and the subsequent continuous emission of 10 μA for 30 minutes. The field-emission pattern and the current stability of surface-processed TiC〈110〉 tips have been investigated for several kinds of surface processing.
