Mapping sp2 and sp3 states of carbon at sub-nanometre spatial resolution.

Discusses the use of transmission electron energy-loss spectroscopy (EELS) to obtain a map of sp2 and sp3 carbon at a spatial resolution of less than a nanometer across the silicon surface. Diversification of applications of diamond by the discovery of the chemical deposition process for film formation; Nucleation of diamond; Nature of carbon bonding at the interface.
