Research subject for a potential FP6 project

The project will focus on multidisciplinary research of mesoscopic scale systems (nanoparticles, subnanometric multilayers) prepared by physical and chemical methods. The main research areas are: magnetic nanoparticles, surface modified nanoparticles, advanced techniques for nanoscale manufacture, self-assembling. The goal of the project will be to develop new complex materials with defined physical properties. Here, also the patterning of substrates or prepared structures can bring new effects.
Our research team has a long-term expertise in preparation and characterization of thin film multilayers. Recently we extended our research to nanoparticles. The physical vapour deposition and laser processing has been used for preparation of multilayer structures, the submicron patterning is performed by electron beam lithography and dry etching. For characterization the X-ray scattering methods (specular reflectivity, diffuse scattering at grazing incidence and X-ray diffraction are the most important experimental techniques. Recently the methods using the synchrotron radiation (GISAXS, EXAFS) have been applied. The main research area is to study the structure, the role of surfaces and interfaces on the physical properties of nanoparticles and nanometric layered systems and to study the self-assembling of nanoparticles deposited onto the substrate under various conditions.
