8 - Ion beam synthesis

Abstract

Ion beam synthesis is a powerful method for the creation of new substances and specific layers in materials. Ion beam synthesis differs from ion beam modification due to its range of implanted fluences. In particular, it is useful for specific structures that cannot be formed by other methods. An example is the ion beam synthesis of metal nanoparticles in polymer surface layers. The metal particles are created by implantation of metal ions into the polymer target. Due to high incompatibility with polymer macromolecules, the implanted metal atoms can diffuse and form metal clusters (particles). The process of particle formation depends on mobility of implanted ions in the polymer matrix. The ion beam synthesis of metal inclusions in the liquid polymer matrix needs follow-up investigation and development, which can bring new physical effects and applications. The ion beam implantation by gas ions with high fluence of implantation could be used for the generation of a new phase in the implanted surface layer of polymers. The final structure of the implanted target depends on initial atomic contamination of the polymer target and on implanting ions. The ion beam synthesis from polymer structures can play a significant role in synthesis of complex shape inorganic nano-structures. Different applications can be found for ion beam synthesis of dewetted polymer and also organic structures.
