Title
Electronic structure of ntype nanocrystalline diamond: An x-ray spectroscopic study (Research)
Abstract
Doping nitrogen or lithium into nanocrystalline diamond (NCD) films improves the electrical conductivity that
promote an enormous improvement in the field electron emission (FEE) and electrochemical (EC) properties of
NCD films. In order to elucidate the FEE and EC properties, it is important to understand the nature of chemical
bonding and the electronic structure of the doped NCD films. To this aim, Xray absorption spectroscopy and
Resonant Inelastic Xray Scattering will be performed at the C K edge and N K edge to study the chemical
bonding and electronic structure of the NCD films. In addition, Photoemission spectroscopy will be used to probe
the C1s, N1s and Li1s core levels and the Fermi edge of the NCD films. Understanding the nature of chemical
bonding and the electronic structure will be crucial for explaining the electron conduction mechanism in the
doped NCD films.
