| The aligned rod formation from spherical metallic nanoparticles embedded in a dielectric matrix produced by swift heavy ion irradiation has been known for many years and it is interesting for many industrial applications. Although diverse experimental and theoretical techniques have already been employed in order to explain this process, it is still not well-understood. One of the reasons that complicate this task is the lack of information concerning the intermediate stages of the deformation mechanism. In this work we have studied the elongation of silver nanoparticles embedded in a silica matrix irradiated with 40 MeV Br ions by means of in situ optical measurements, TEM and molecular dynamics simulations. The agreement between these techniques is excellent. We have analyzed the nanoparticle deformation after several impacts with different ion energies, and studied the influence of Ostwald ripening, internal stress and heat diffusion. | |
