Abstract: Bias enhanced
nucleation was explored in order to obtain a high diamond nucleation
density on Mo and CrN coated stainless steel substrates in a
hot-filament chemical vapor deposition (HFCVD) reactor. Several bias
geometries were tested on their nucleation enhancement for diamond on
molybdenum. It was found that the nucleation properties observed for Mo
were not much different for CrN coated stainless steel. The application
of a bias between the filament and acathode above the substrate at
floating potential resulted in locally high diamond nucleation
densities of up to 3.10(9) cm(-2).
