Patent ID: 7544547

Claim:
Method for producing a support comprising nanoparticles for the growth of nanostructures, said nanoparticles being organised periodically, the method being characterised in that it comprises the following steps: providing a support comprising, in the vicinity of one of its surfaces, a periodic array of crystal defects and/or stress fields, depositing, on said surface, a continuous layer of a first material capable of catalysing the nanostructure growth reaction, fractionating the first material layer by a heat treatment so as to form the first material nanoparticles, wherein the periodic array of crystal defects and/or stress fields has a period chosen according to the natural self-organisation period that the nanoparticules would have on a surface of a support free of any crystal defects and/or stress fields and wherein the step of providing the support is achieved by carrying out the following steps: bonding by molecular adhesion a surface of a first substrate made of a crystalline material with a surface of a second substrate made of a crystalline material, so that said surfaces have offset crystal lattices, the bonding causing the formation of an array of crystal defects and/or stress fields in the vicinity of the bonding interface, thinning one of the substrates until obtaining a thin film adhering to the other substrate according to the bonding interface, the thickness of the thin film being such that its free surface reveals the presence of the array of crystal defects and/or stress fields.
