About Us

The interaction of particles with solids can produce high levels of damage influencing drastically the behaviour of materials. This is a major issue for materials operating under extreme radiation conditions like space (satellites) and nuclear reactors. The research activities of the group in this area are internationally recognised and the work on nitrides a reference in several aspects. The studies of implantation damage associated with the doping by ion implantation stays a very important topic of our research portfolio. The search of materials to make sensors to measure single ion impacts is an important field for quantum computing technology based on deterministic ion implantation doping. Another important area where radiation effects of particles are very important are biomedical applications of particles for cancer therapy. This is an emerging area in which the group would like to engage in the future.

PFC-MAT Project Plasma Facing Components - Materials: materials facing the plasma will be hit by a cloud of highly charged and neutrals particles depositing large quantities of energy and affecting their integrity. To understand the processes operating during these interactions we produce the materials which will be used in the fusion reactors and mimic in laboratory the effect of the plasma to test their behaviour.

WBGM Project Wide Band Gap Materials: the group has been involved in research projects to investigate the damage build-up processes during ion irradiation and to test their performance as radiation detectors and LED's.
