Project A02 - Leiderer, Boneberg

Funding period: 2008 – 2011

Principal investigators: Paul Leiderer, Johannes Boneberg

Scientific staff: Tobias Geldhauser, Andreas Kolloch, Markus Schmotz

The project aims at studying mechanical properties of nanostructures by surface acoustic waves (SAW) in the high GHz range, which so far has not been experimentally accessible. In order to generate these waves, nanostructured substrates will be irradiated with short laser pulses, which due to several processes gives rise to fast mechanical local deformations of the small structures. The emitted SAW will then be used for acoustic spectroscopy and manipulation. The long-term goal is to establish in this way a new, sensitive tool for characterizing and controlling nanostructures.
