Research Activity
IBA methods are important and indispensable techniques for thin film analysis. The qualitative and quantitative data which could be received with MeV energy Ion Beams are very useful in the modern thin film research, and they are irreplaceable at the moment.
The Fe-Ag system is well studied in both thin film and granular structure. The two elements are immiscible even in liquid state. The difference in the atomic masses of the two elements give an excellent possibility to study the growth mechanism, performing structural characterization and tracking the changes and responses for different structural modification procedures via IBA methods (heat treatment, ion implantation).
