ABSTRACT:
A composite element is disclosed, having improved heat conductivity, and is composed of a substrate whose surface layer enables homeo- or heteroepitactic growth of the diamond lattice from the gas phase, and of a low pressure diamond layer grown on the substrate, and in which the diamond layer grown is enriched compared to the normal diamond composition in the carbon isotope C.sup.12 and depleted in the heavier carbon isotopes C.sup.13 and C.sup.14.
