The talk will be given in English.
Material structures with nano-scale dimensions, such as thin layers, wires, pores, composites or an ensemble of tiny precipitates, have many interesting functional properties making them of great interest for a wide range of applications.
Fabrication of well-defined nanostructures is still a major challenge and many diverse approaches and methods are used to create nano-structured materials. Many unique properties are related to nano-structures, and understanding the correlation between the material properties of a system and its nanometre-scale structure is critical for the fabrication of novel functional materials. Characterising and analysing materials on a nano-scale is therefore of fundamental importance for advanced material science.
In this talk I will discuss the possibilities of using ion beams within material science to create and even analyse structures on the nano-scale. I will show examples of nano-structures, having interesting chemical and physical properties, which have been created in a wide variety of materials by different types of ion technologies. Possible applications of the created structured material will be presented. Furthermore, examples of investigating and analysing tiny material features using ion beam analytical instruments will be demonstrated. Advantages and disadvantages, different effects and problems occurring using the presented ion techniques will be discussed.
