dc.description.abstractThis work comprises studies addressing fundamental questions of the diamond surface physics for different doping concentrations of nitrogen and boron, and how doping is reflected in the core shell analysis, valance band structure and work function values. A second aspect of the work is the controllable creation of nitrogen-vacancy (NVs) centers accompanied by comprehensive surface spectroscopy studies (XPS,UPS and MIES). Additionally, in order to increase and stabilize NV negative (NV-), which are required for quantum computing system, studies on diverse oxygen termination procedures has been executed. The efficiency of oxygen termination procedures compared and is confirmed by spectroscopy and wet contact angle (WCA) measurements. Furthermore, an alternative method of hydrogen termination of the diamond surface is proposed and compared to the traditional hydrogen plasma termination. As related side aspect, the deposition of C60 molecules on the diamond surface is performed and investigated by means of UPS and MIES spectroscopy. A distinctive experimental capability of studies is the implementation of the Metastable Impact Electron Spectroscopy (MIES) spectroscopy. This unique surface spectroscopy technique and individual instrumentation design for probing the electronic structure of the outermost surface layer, including measurement examples is introduced in this work.eng
