Abstract

A method of causing the growth of crystals in the form of crystalline filaments on a substrate, in a gaseous atmosphere that contains the substance to crystallize or its components, in which a significant growth of anisotropic crystals is stimulated by nucleation of the substrate, characterized in that the crystals are grown on a substrate that is rough, at least superficially, due to the presence of crystallites that protrude from the surface, the lateral dimensions of said crystallites on said surface corresponding, approximately in size, to the thickness of the crystals that have to grow.
