Development of Femtosecond Timeresolved Scanning Probe Microscopy and Related Techniques

Research Project Outline

Ultrashort optical pulse technology has allowed us to observe transient phenomena in the femtosecond range, namely, the optical-monocycle region, which, however, has the drawback of a relatively low spatial resolution due to the electromagnetic wavelength used. On the other hand, scanning tunneling microscopy and its related techniques, although having a time resolution limited by the circuit bandwidth enables us to observe spatial dynamics at the atomic level in real space. Our purpose here is to combine these two techniques to achieve a new technology which will advance the pursuit of future nanoscale scientific research in terms of the ultimate temporal and spatial resolutions.
