These crystalline - promising for the spintronics - materials are prepared as nanolayers by the low-temperature molecular epitaxy and their properties are affected by the sample surfaces. Surface sensitive methods provide information about the crystallography of their reconstructed surfaces and about their electronic and magnetic properties.

Our focus is on qualitative and quantitative understanding of relation between geometric and spectroscopic properties of materials, with special emphasis on clusters and nanostructures. Studying these materials is interesting both for fundamental reasons (they form a link between atoms and solids) and for practical reasons (because of potential use of these materials in information and other technologies).

Hardness and stiffness of materials are different quantities describing properties of solids. Stiffness describes how much it resists being temporarily stretched or compressed, springing back when force is released. In contrast, its hardness is resistance of material to permanent shape change, which happens when atoms are pushed to new locations.  The whole text »

Protein crystallography is one of the key techniques of structural biology and is focused on determination of three-dimensional structure of proteins or nucleic acids by the means of single crystal x-ray diffraction.  The whole text »

OD structures (abbreviated from Ordered-disordered) are composed of layers, either corresponding to real structure building units, or formally selected. The structure is built up of stacking of these layers according to the law known as the vicinity condition, representing a set of special operations – shifts and/or rotations. This condition is ambiguous, that means that always exists more than one possibility how the consecutive layers can be stacked.  The whole text »
