Abstract

This study reports direct imaging of electron emission from two different classes of diamond containing films that were prepared by microwave plasma chemical vapor deposition. These are N-doped, and nanostructured diamond containing films. The electron emission is excited by UV light (photoemission) or by an applied field (field emission). The photo electron emission microscopy (PEEM) of the N-doped films exhibited uniform emission, and upon heating to ~ 700°C, field electron emission microscopy (FEEM) of the films showed similar uniform emission. In contrast, FEEM of the nanostructured films showed high brightness, localized emission sites at room temperature. The results indicate different processes for electron emission from nanostructured and N-doped diamond films.
