Emitting Carbon Thin Films and Their Characterizations
Published online by Cambridge University Press: 10 February 2011
Abstract
Carbon thin film cathodes have been produced with an emission site density of 2 × 105/cm2 and with current density higher than 40 mA/cm2at 10 V/μm extraction field. Characterization of the film bonding structure by UV Raman spectroscopy and emission sites by Atomic Force Microscopy (AFM) are presented and discussed in detail. A hypothesis of the nature of emission sites in these films is proposed in accordance with the analyses.
