Abstract

Electron emission measurements on diamond films synthesized by chemical vapor deposition are reported. UV photoemission spectroscopy indicates that the samples exhibit a negative electron affinity after exposure to hydrogen plasma. Secondary electron emission yields vary from 2.2 to 9.2. Field emission current-voltage measurements indicate threshold voltages ranging from 28 to 84 V μm-1. The film with the highest secondary yield also exhibits the lowest emission threshold.
