Abstract

The work demonstrates the possibility of obtaining material containing micron-size diamond single crystals with a regular pyramidal shape surrounded by a low-order diamond fraction by plasma-enhanced deposition (CVD). To study the morphology of these films, the selective oxidation technique followed by an analysis of its results by electron microscopy and Raman spectroscopy is applied. We propose a model that describes the formation of these films. The possibilities to use the materials of this type are also discussed.
