Outline of Final Research Achievements

Visualization and control of atomic and molecular motions in the nanometer scale has been very difficult because the dynamics associated with the nanoscale is in the range of picoseconds or femtoseconds. To investigate such a ultrafast timescale in the nanoscale, we combined the scanning tunneling microscope with the terahertz spectroscopy. As a result, we succeeded in observing the picosecond and femtosecond electron tunneling in the nanogap and the photoincuced phase change at the nanoscale. These results could be very useful for the future nano-electric devices.

Academic Significance and Societal Importance of the Research Achievements

テラヘルツ時間領域分光法と走査型トンネル顕微鏡という超高速の時間スケール、かつ微細な空間スケール（ナノスケール）での分光を可能にする技術を組み合わせることによって、従来は不可能であったナノスケールでの物質層の制御や観測が可能となった。この結果によって、電子の授受を伴う表面化学反応や、超高速デバイスの新動作原理、ナノスケールの相変化ダイナミクスなどにおいて新しい研究ツールとなる技術が開発された。これらの分野の研究を通して、ダイナミクスの理解が進むことによって、反応の効率化やデバイス設計、物質設計などに新たな知見をもたらすことが期待される。
