High Frequency Acoustics in Colloid-Based Meso- and Nanostructures by Spontaneous Brillouin Light Scattering W. Vogel & M. Büttner GmbH Wandel in der Krankenhaussozialarbeit25Materials that can mold the ? ow of elastic waves of certain energy in certain directions are called phononic materials. The present thesis deals essentially with such phononic systems, which are structured in the mesoscale (\1 lm), and with their individual components. Such systems show interesting phononic properties in the hypersonic region, i. e., at frequencies in the GHz range. It is shown that colloidal systems are excellent model systems for
