Members of research program have published over 250 SCI papers in last five years, over half are assigned A'. Over 30 papers are assigned A''. Within scientific achievements we list typical ones only. The paper was published in a prestigeous physical journal with impact factor over 7. In collaboration with a couple of foreign European fusion centres we managed to suppress the tritium retention using synergistic effects of plasma particles produced from reactive gases.

We reported on the chemical synthesis of the arrays of silicon oxide nanodots and their selforganization on the surface via physical processes triggered by surface charges. The method based on chemically active oxygen plasma leads to the rearrangement of nanostructures and eventually to the formation of groups of nanodots. This behaviour is explained in terms of the effect of electric field on the kinetics of surface processes. The direct measurements of the electric charges on the surface demonstrate that the charge correlates with the density and arrangement of nanodotswithin the array.

An important activity of the program group is devoted to a rapidly growing field of interdisciplinary research - plasma biomedicine. This particular paper was published in a prominent journal speciallized in plasma surface engineering of polymers. We showed clearly that even traces of blood proteins can be removed from surfaces of catheters using neutral oxygen atoms which are created by lowpressure electrodeless gaseous discharges. The treatment is benign to catheters themselves so the method is suitable for application in medical praxis.

In magnetron sputtering the material is sputtered from a target and deposited on the areas of substrates that are in the lineofsight of the vaporization source. In industrial deposition systems the substrates are normally fixed on a turntable, which performs a planetarytype of rotation. In this work, our previously developed simulation of coating growth in an industrial deposition system with a planetary type of rotation has been used to analyze the influence of the rotation and target arrangement on the uniformity and periodicity of layered coatings. Results of simulations show that highly periodic modes of rotation, which are determined by the turntable gear ratio and the switch angle, cause large nonuniformities both in the thickness and the composition of layered coatings. On the other hand, less periodic modes of rotation produce better coating uniformity although for certain rotation parameters significant nonuniformities may also occur. The simulation has attracted interest of researchers and several companies, and resulted in signing a research contract with one of the largest manufacturers of PVD systems for deposition of hard coatings. As our research group is one of the world's leading on the topic of growth defect diagnostics, our coworker Dr Peter Panjan had an invited lecture at the International Conference of Metallurgical Coatings and Thin Films in San Diego, USA.

Focused ion beam induced mixing was studied in a hybrid C/Si/C/Si/C/Si multilayer structure, where amorphous SiC thin film with thickness in the nanometer range was produced. The ion irradiation induced a slightly asymmetric intermixing of the top C and Si layers. During ion mixing, part of the intermixed C and Si atoms reacted, forming amorphous SiC. The amount of SiC depends on the square root of the ion fluence.
