<p><P>PROBLEM TO BE SOLVED: To provide a method for providing at least one catalyst nanoparticle on at least one sidewall of a three-dimensional structure on a substrate, and an excellent method for forming an elongated nanostructure by using the catalyst nanoparticles as the catalyst. <P>SOLUTION: The method comprises providing at least one catalyst nanoparticle 8 on at least one sidewall 10 of the three-dimensional structure on a main face 15 of the substrates 1a, 1b, the main surface 15 being in the face, the side wall 10 of the three-dimensional structure being in a face roughly vertical to the main face of the substrates 1a, 1b; obtaining the three-dimensional structure including catalyst nanoparticles 7 embedded in a non-catalytic matrix 5; and selectively removing at least part of the non-catalytic matrix 5 at the sidewalls 10 of the three-dimensional structure to thereby expose at least one catalyst nanoparticle 8. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
