181Hf(181Ta) and 77Br(77Se) PAC measurements in calcium fluoride — •Thomas Geruschke and Reiner Vianden — HISKP, Universität Bonn, Nußallee 14-16, 53115 Bonn
Calcium fluoride is nowadays not only used in optical applications like lenses or windows for UV-laser. Nanostructures on silicon are produced with calcium fluoride masks and even as dielectric gate material in organic thin films transistors (OTFTs) it get more and more important.
To achieve more information about defects and the material itself we use the perturbed angular correlation method (PAC). First results of the annealing behaviour of the implanted probe ions 181Hf(181Ta) and 77Br(77Se) are presented and discussed.
