Abstract
We have fabricated two type of graphite field emission cathodes: graphite nanospines (GNS) and graphite field emitters inflamed at high temperatures (GFEIHT) and applied for X-ray tubes using these cathodes. The morphologies and structures of the two cathodes were quite different. However, these emitters have excellent field emission characteristics. Raman spectroscopy indicated that GFEIHT consisted of many graphene tips without crystalline defects.
