<p>A method of manufacturing a diamond layer having a porous three-dimensional structure, the method being of the type which includes growing the diamond layer from a sacrificial material and gradually decomposing said sacrificial material during growth of the diamond layer, said material including the following steps; 1) provision of a substrate capable of supporting the plasma-enhanced chemical vapour deposition growth of the diamond layer on at least one of the surfaces of of the substrate, the substrate comprising, on said at least one surface thereof, a layer made of a sacrificial material having a porous three-dimensional structure capable of gradually decomposing upon contact with said plasma, the layer of sacrificial material containing diamond grains of nanometric size, and 2) growth by plasma-enhanced chemical vapour deposition of the diamond layer from diamond grains and concomitant and gradual decomposition of the scrificial material upon contact with said plasma.</p> |
