Abstract
A composite structure having a substantially monocrystalline growth substrate and at least one monocrystalline or polycrystalline layer of diamond or diamond-like material arranged on a surface of the growth substrate, the surface of the growth substrate being provided with crystal growth nuclei having crystal axes which exhibit an inclination of not more than 10%, preferably not more than 7%, with respect to corresponding axes of the crystal lattice of the growth substrate, and a process for producing such a composite structure in which the growth substrate is pretreated and growth nuclei are deposited from a nucleating gas phase of known composition for depositing layers of diamond or diamond-like material, in which during the nucleation the growth substrate is raised to a negative electrical potential relative to the nucleating gas phase.
