Riassunto
By the deposition of a cold Cesium
atomic beam, we pattern nanostructures in a controlled way by a
1dimension Standing Wave. Different substrates as graphite, gold,
silicon have been used with direct deposition or by resist assisted atom lithography. One of the main efforts of the experiment
is using cold atoms generated by a Magneto Optical Trap, and,
investigate the sample ex-situ (after resist assisted deposition)
or in vacuum by STM. The deposition of ultra cold atoms is
important not only for studies cooling mechanisms and
nanolithography limits but also became a new challenge for the
surface physics to explore the dynamics of a single atom over a
substrate.
