| Outline of Final Research Achievements |
We have succeeded in depositing Pt nanowire array of 2nm wirewidth and 7nm periodicity by shadow deposition on MgO(210) facetted templates. The SHG intensity from this Pt nanowire array is several tens of times stronger than that of wirewidth of 7nm. We guess one of the candidate origin of this SHG enhancement is the quantum confinement effect of the electron in the nanowire structure. We also observed moire structure in the TEM image of Pd nanowires on the MgO(210) facet. We have also succeeded in making a Au/stepped TiO2(320) sample. We are now measuring the SHG response from these samples. We have also obtained interesting microscopic information from nanofabricated structures on Cr films and hydrogenated stepped Si(111) surfaces.
