ABSTRACT
The bias-enhanced nucleation (BEN) of diamonds on a Si substrate, using a SiO[sub 2] mask and microwave plasma-enhanced chemical vapor deposition (MPE-CVD), was examined. Experimental results indicate that the electron-emission-enhanced nucleation mechanism proposed herein governs the nucleation of diamonds on the partially patterned SiO[sub 2]/Si substrate. The variation of nucleation density on the partially patterned SiO[sub 2]/Si substrate also reveals that the BEN of diamonds in the MPE-CVD process follows the proposed mechanism. © 2001 American Institute of Physics.

    A fine structure was discovered in the low-energy peak of the secondary electron emission spectra of the diamond surface with negative electron affinity. We studied this structure for the (100) surface of the natural type-IIb diamond crystal. We have found that the low-energy peak consists of a...
