Title Ion beam analysis study of crystalline structures
Název Využití iontových svazků při studiu krystalických struktur

Main aim of the project is the characterization of the structures based on LiTaO3, single crystal SrTiO3, BaTiO3 and KTaO3 doped Pb, Mg materials using ion beam analysis. Crystalline structures investigated in this research are very promising for the preparation of planar lasers or are applicable in microelectronics - high permittivity materials. The dopant depth profiles, stoichiometry of crystalline structures will be measured by RBS, ERDA and PIXE.The positions of the interstitial dopants in doped crystals and the crystal modification under the used  deposition technologies can be determined by the innovative analytical technique (RBS-channeling) and the crystal lattice changes will be studied by comparative method XRD in collaboration with Forschungzentrum Rossendorf. The important part will be the study of superlattice structures and their interfaces using RBS-channeling. The results of the above mentioned analyses will be confronted with properties of the prepared structures.
