Abstract
Electron emission measurements on diamond films synthesized by chemica l vapor deposition are reported. UV photoemission spectroscopy indicat es that the samples exhibit a negative electron affinity after exposur e to hydrogen plasma. Secondary electron emission yields vary from 2.2 to 9.2. Field emission current-voltage measurements indicate threshol d voltages ranging from 28 to 84 V mu m(-1). The film with the highest secondary yield also exhibits the lowest emission threshold.
