Abstract : With a goal towards an understanding of how nucleation of diamond growth can be beneficially enhanced, our research has concentrated on how different types of surface passivator might positively impact diamond nucleation and growth. We have focused these studies on the fluorinated and hydrogenated (100) surfaces, which have some chemical similarities (and some differences) but have considerably different sizes. With a view towards alternative passivation of the diamond surface, we have initiated work on boron-doped and beryllium-doped diamond (100) surfaces. The idea here was to investigate how atoms other than carbon could maintain an unreconstructed diamond (100) surface but lead to better growth and nucleation rates. The working assumption is that better growth rates will be obtained if passivators prevent surface reconstruction but promote the adsorption of carbon in four-fold configurations.
