Bachelor thesis

Bonding of nitroxyl organic radicals to polycrystalline surface of cerium oxide

In this bachelor's thesis we propose to study the bonding of nitroxyl organic radicals on the polycrystalline surface of cerium dioxide, a material with very promising properties for bioapplications and organic electronics. The model system will be prepared in vacuum by deposition of nitroxyl molecules from the Knudsen cell on the oxide surface. The morphology of the CeO2 layer prepared ex situ by magnetron sputtering will be analyzed by microscopic technique (AFM). The interaction of molecules with the CeO2 surface will be studied using XPS, SRPES, RPES and NEXAFS spectroscopies at the Czech MSB beamline of Elettra synchrotron in Trieste, Italy.

The aim of this work will be to study the way in which nitroxyl organic radicals interact with the polycrystalline surface of cerium dioxide.
