Here, we present results concerning molecules and their charge-state determination and control on multilayer NaCl films. We demonstrate lateral single electron transfer between molecules (1) and gain insight into charging processes via single-electron tunneling spectroscopy, where we quantify the reorganization energy of a molecule on a NaCl substrate (2). Finally, we show results where the charge state of a complex on top of an insulator plays a key role for its on-surface chemical reaction.

The red-light emitting phosphors get more and more attention in the recent years due to various applications, one of the most important of which is related to the solid state lighting and white light emitting diodes (LEDs). The currently used white LEDs suffer from the lack of the red component, which results in the high color correlated temperature (CCT) and low color rendering index (CRI). The phosphors based on the red emission of the Mn4+ ions are excellent candidates for improvement of the white LEDs characteristics. The advantage of these phosphors over those based on the Eu3+ and Sm3+...

A new anticorrosion strategy for Zr nuclear fuel claddings will be presented and explained. The dissertation deals with a protection of zirconium (Zr) nuclear fuel cladding material against corrosion in water-cooled nuclear reactors by coating by polycrystalline diamond (PCD) or chromium-aluminum-silicon nitrate (CrAlSiN) layers. It was shown that Zr alloy surfaces can be effectively protected against oxygen and hydrogen uptake at both accident and working temperatures in water-cooled nuclear reactor environments by coating the Zr surface by PCD layer or CrAlSiN each in specific way and for...

The modern version of the KKR (Korringa–Kohn–Rostoker) method represents the electronicstructure of a system directly and efficiently in terms of its single-particle Green's function. Direct access to the Green function results in several appealing features. In particular the description of the electronic correlations, disorder and electronic spectroscopies for the nanosystems and surfaces has been developed in the recent years. In the first part of my talk I will review basic ideas of the multiple scattering KKR formalism. Second part will be devoted to the Angle-resolved photoemission...
