In our first application of this new technique, we addressed one the fundamental puzzles of diamond film growth. "Why does the the growth of diamond films appear to depend so little on chemical structure of the reactant (or feed) gases?" Using this new method, we have found that within the plasma a rapid interconversion of carbon containing species occurs. In other words, although the feed gases may initially have different chemical natures, the plasma rapidly scrambles them into an almost identical mixtures of reactive species, which is ultimately responsible for film growth.
