Sažetak
Materials modifications using swift heavy ion beams provided by large scale accelerators have been used for many years in a wide variety of ways, e.g. to produce ion tracks or to modify shape of nanoparticles. In all this applications the most relevant parameter for materials modification is electronic stopping power and not the ion total kinetic energy. For many materials, ions delivered from the medium and small size accelerators have sufficiently high values of electronic stopping power to modify materials in different ways. In the present contribution, we review recent experimental and theoretical achievements of the Zagreb group in this field. These include swift heavy ion tracks in SrTiO3 [1], [2], development of single ion irradiation setup [3] and ion beam assisted formation of ordered QD arrays [4]. In all cases, ion beams delivered from the 6 MV Tandem Van de Graaff accelerator based at RBI, Zagreb have been used. Together with experimental work, we present thermal spike model, which was applied to describe obtained features. Recent description of highly charged ion tracks using an extension of the thermal spike model is also presented
