Short description of company<br />

The group studies the fundamental physics of novel materials under dimensional constraints. This includes<br />

investigations of their formation, structural evolution and the physics of their unique properties. Multiscale<br />

phenomena of metals, alloys and polymers with nanocrystalline structures (grain size < 100nm) and with<br />

geometrical dimensions smaller than 100 µm are studied using state-of-the-art complementary experimental<br />

methods such as atomic resolution transmission electron microscopy and scattering with synchrotron radiation,<br />

atomic force microscopy and contact-free laser speckle correlation. The scientific expertise and the unique<br />

facilities developed by the research group enable the analysis of thermomechanical properties of materials with<br />

small dimensions. Investigations are carried out to analyse the physical mechanisms of phase stability,<br />

disordering, nanocrystallization and amorphization. The experimental results are modelled in terms of the size<br />

constraints, internal stresses, lattice defects. The results are used to optimize the thermomechanical, magnetic<br />

and electric properties especially of bulk nanocrystalline materials obtained by severe plastic deformation and of<br />

microelectro-mechanical systems. The important physical aspects will lead to the development of new micro and<br />

nanosystems for innovative technological applications.<br />
