Outline of Final Research Achievements

Scanning probe microscope is capable of observing an atom by using very sharp probe. Not only obseving an atom, the microscope can move an atom one by one by using the probe. Here, we assembled two scanning probe sicroscopes, realized an atomic-size switch on STO insulating substrate. In addition, on TiO2 insulating substrate, we found that microscopic atomic structure affect to the macroscopic electrical transport. The final goal of this research proposal, development of 4-probe scanning tunneling potentiometor which is capable of visualizing atomic scale electrical transport, has made great progress,

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み、より高速でより大容量になるなるなど性能の向上が劇的に進んでいる。しかしながら、このようなトップダウン式のやり方は微細化が原子スケールに近づくにつれて限界を迎える。そのため、原子一つ一つから素子を組み立てるボトムアップ式のナノテクノロジーが注目されている。そこで重要となるのが、原子スケールでのエレクトロニクスの基礎の科学である。
研究成果のSTO基板上の原子スイッチは、原子数個のメモリーであり、その基礎となる。さらに、TiO2基盤上の電気伝導や開発進行中の4探針STPは、原子スケールの構造がマクロな電気伝導にどのような影響を与えるかを明らかにする。
