... have been used as catalysts. During the thermal treatment of the samples, thin films of the metal catalysts are transformed in small nanoparticles incorporated within the pore structure of the ... Si surface. Since the nanoparticle size of the patterned catalyst is uniform, the grown nano- wires are also uniform in diameter. The averaged pore size of the alumina...
