The authors would like to thank Drs. D. Doerr and D. Alexander in the Department of Electrical Engineering at the University of Nebraska-Lincoln (UNL) for providing convenient access to their SEM system. The home-made Raman system was built by K.J. Yi, whom the authors would like to thank for his great efforts. This work was financially supported by the U.S. Office of Naval Research (ONR) through the Multidisciplinary University Research Initiative (MURI) program.

N2 - Diamond nucleation and growth in the combustion-flame method were monitored in real time using thermionic emission current from the deposited diamond films. It was observed that the emission current evolved over three periods, the incubation, the fast increase, and the saturation periods. Ball-shaped diamond particles, faceted diamond crystals, and diamond films with well-faceted crystals were formed in the three periods. The current from a diamond-seeded substrate started to increase immediately without an incubation period, confirming that the current is from the diamond. Therefore, the current could be used for real-time monitoring of the diamond nucleation and growth.
