| Scanning tunneling microscopy/spectroscopy as well as atomic force microscopy were applied to study the non-structural and nanoelectronic properties of periodic nickel nanoparticles deposited on n-silicon substrates. Periodic nickel (Ni) nanoparticles were prepared by using nanosphere lithography and analyzed by scanning tunneling microscopy/spectroscopy and atomic force microscopy. By the evaporation of Ni perfectly ordered nanoparticles were produced and very good correlation between latex mask was observed. Finally, tunneling spectroscopy performed with non-magnetic tip yield information about local electronic properties of nanoscale structures at surface. |
