ABSTRACT:
The invention relates to a process for synthesizing nanorods of a carbide of one metal M1on a substrate, which comprises:a) the deposition, on the substrate, of a layer of nanocrystals of oxide of the metal M1and nanocrystals of oxide of at least one metal M2different from metal M1, the M1metal oxide nanocrystals being dispersed within this layer;b) the reduction of the M1and M2metal oxide nanocrystals into corresponding metal nanocrystals; andc) the selective growth of the M1metal nanocrystals.The invention also relates to a process for growing nanorods of a carbide of one metal M1on a substrate from nanocrystals of this metal, to the substrates thus obtained and to their applications: fabrication of Microsystems provided with chemical or biological functionalities, in particular the fabrication of biosensors; electron emission sources, for example for flat television or computer screens; etc.
