@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.
