| Outline of Final Research Achievements |
Scanning probe microscope is capable of observing an atom by using very sharp probe. Using the probe, the microscope can move an atom one by one. Here, we assembled a scanning probe microscope, and fabricated an atomic-size switch consisting of only four silicon atoms. It was found that two silicon atom switches were affecting each other when they were very close to each other.

| Academic Significance and Societal Importance of the Research Achievements |
近年、半導体素子の微細化が急速に進んでいるが、そろそろ限界にきている。そのため、原子一つ一つから素子を組み立てるナノテクノロジーが注目されている。シリコン原子スイッチは原子数個でできていり、問題を根本的に解決する一歩となる可能性がある。さらに、相互作用があることから、原子レベルでの計算に応用できる。さらに、シリコンに代わる次世代材料であるグラフェンやトポロジカル絶縁体においても、その探求を行った。
