Abstract

A growth substrate having growth nuclei made of diamond and/or diamond-like carbon arranged on its growth surface, the orientation of over 50% of the growth nuclei deviating by less than 10.degree. from the crystal orientation defined by the growth substrate corresponding to Miller's indices (h, k, l) and the nucleus density changes between the center of the growth substrate and a distance of maximally 15 mm from the center by maximally 80%. The method also relates to a process for the growth substrate's manufacture.
