270090 VO Spectroscopy of interfacial layers (2006W)

F212: elective field of concentration in analytical chemistry and matter chemistry
Content: Interfacial layers have important electrical properties, serve in catalytic processes, chemical sensing, materials for separation technology, matter transport and selection and especially in biomembranes. Optical multi reflection methods, as well in the visible as in the infrared range, and ESCA, Auger- and electron loss spectroscopy and SIMS, but also Mößbauer spectroscopy permit a thorough analysis and structure elucidation of surfaces. New dimensions are revealed by scanning tunnelling microscopy, atomic force microscopy and scanning near field optical microscopy, which are capable of atomic resolution.
