Outline of Final Research Achievements |
We present a simple technique for simultaneous control of the electrical properties of multiple Ni nanogaps. This technique is based on electromigration induced by a field emission current and is called "activation". Simultaneous tuning of the tunnel resistance of multiple nanogaps was achieved by passing a Fowler-Nordheim (F-N) field emission current through an initial group of Ni nanogaps connected in series. Furthermore, Ni-based single-electron transistors (SETs) operating at room temperature were successfully fabricated and integrated using activation method. These results clearly imply that electromigration procedure allows us to easily and simply integrate Ni-based SETs.
