Electron emission at remarkably low electric fields has been reported from a wide variety of carbon films over the past decade. Although the precise mechanism of emission is still under debate, it is becoming clear that graphitic phases of carbon play a central role in the origin of the low-field emission properties of carbon-based cold cathodes. In this work, we use conventional diode type apparatus to measure broad-area emission characteristics, and field emission microscopy to investigate and identify the carbon phases associated with field emission. We demonstrate that purely SP2 carbon films can be excellent field emitters. We relate the differences in broad area field emission characteristics and in field emission microscopy images in terms of film morphology and the field emission physics of various carbon phases. .
