Materials Research at GSI Welcome to the website of the Materials Research Department. The Materials Research (MAT) Department of GSI contributes, together with 5 other Helmholtz centers, to the Research [...] applied research related to the irradiation and characterization of materials. Our research is focused into three pillars: Ion-track nanotechnology, Heavy ion-induced modifications of materials from bulk [...] astrochemistry, radiation hardness of materials and devices, materials under high-pressure and nanoscience. We investigate a wide variety of materials comprising organic materials, ceramics, semiconductors, (s
