About Us

Ion beam technologies have been used for materials processing since the dawn of the transistor era. The first applications on the study of silicide growth to make transistor contacts remain as major step. Actually, the great capabilities of ion beam techniques make them very useful for studies in areas as environment, biomedicine, geology and cultural heritage. The members of the Group established a network of collaborations with researchers from all over the world to perform studies on this areas taking advantage of the non-destructive and quantitative nature of the ion beam techniques. As an example, the study of the painting materials employed by XVII century artists that exploited copper as a support for oil is worth to be mentioned. Other important research work in being performed in collaboration with the University of Minho on biomaterials and coatings.

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

Implantation damage build-up curves measured along these crystal directions revealing strong radiation resistance and channelling patterns along the a, c and m axes in GaN.

MEC Project Materials for Energy Conversion: high solar absorption can be achieved using coating with a graded refractive index and extinction coefficient and the study of these systems are at the core of the project.

Simulated and experimental reflectance curves of the absorber in the figure as well as the RBS spectra of the as deposited stack, after air annealing at 400 °C and vacuum annealing at 600 °C, both for 650 h.

JET2 Project Joint European Torus 2: study of the physics underlying all the processes related with the plasma wall interactions. The group is responsible for the analysis of marker tiles and passive diagnostics components from the main chamber and divertor of JET.
