Studies of the Structure and Electrocatalytic Reduction of Oxygen on Modified Electrode Surfaces
… mechanism of the electroreduction of oxygen on Au surfaces in basic media is examined using SERS and density functional theory calculations. The spectroscopy reveals superoxide species as a reduction intermediate, while no peroxide is detected. The spectroscopy also shows the presence of …

Tunneling spectroscopy of highly ordered organic thin films
In this work, a Au(100) single crystal was used as substrate for organic molecular beam epitaxy. Highly ordered organic thin films of the molecules 3,4,9,10-perylenetetracarboxylic-3,4,9,10-dianhydrid (PTCDA) and hexa-peri-hexabenzo-coronene (HBC) as well as organic-organic heterostructures on …

Von der organischen Heteroepitaxie zu organisch-organischen Heterostrukturen
… (PTCDA) und Peri-Hexabenzocoronen (HBC) auf verschiedenen einkristallinen Oberflächen von Gold und Graphit untersucht. Zur Abscheidung der Moleküle und zur Herstellung dünner hochgeordnerter organischer Schichten wurde eine Molekularstrahlepitaxieanlage mit mehreren Kammern aufgebaut. Bei …

Chemical bath deposition and electrodeposition of epitaxial semiconductor materials for application in photovoltaic devices
… the epitaxial zinc oxide is reported grown on Au(100), (110), and (111) single crystals. Paper III involves the electrodeposition of epitaxial cuprous iodide thin films on single crystalline Au(100) substrate from a slightly acidic Cu(II)-EDTA-KI solution. The electronic property of the so …

Epitaxial nanolayers of large organic molecules
… Wachstum von großen organischen Molekülen auf kristallinen Substraten mit Hilfe der Quaterrylenderivate QT, QTCDI und QTCMI untersucht. Um derartige Schichten herstellen und charakterisieren zu können, wurde eine Organische Molekularstrahlepitaxy (OMBE)-Anlage aufgebaut. Allerdings stellt …

The effect of free chlorine and monochloramine on lead in drinking water and epitaxial electrodeposition of tin sulfide
… SnS nanodisks were electrodeposited onto a Au(100) substrate. Water utility systems use either free chlorine or monochloramine in their disinfection program. Whereas free chlorine reacts with natural organic matter in the water to produce halogenated organic byproducts that are suspected to …

Investigation of the Surface-Electrolyte Interface of Semiconductors and Metals
… assembly of 2,2’-bipyridine molecules on both Au(100) and Au(111) surfaces using a newly developed SHINERS technique. We present potential dependent SHINERS spectra of 2,2’-bipyridine adsorbed on both surfaces collected under anodic as well as cathodic polarization. A series of processes were …

Surface studies using spin-polarized ion neutralization spectroscopy
… that the polarization of electrons ejected from Au(100) and Cu(100) is strongly correlated with incident ion polarization. The incident ion, in essence, locally magnetizes the surface, creating a net polarization in the local occupied density of states on the surface. Recent experiments on a …

Optische Eigenschaften ultradünner PTCDA & TiOPc Einzel- und Heteroschichten
… im Mittelpunkt. Der realisierte optische Aufbau ermöglicht es, die optischen Eigenschaften von molekularen Sub- und Multilagen während der Schichtabscheidung im Ultrahochvakuum (UHV) zu bestimmen. Eine Strukturuntersuchung kann so unmittelbar darauf im UHV durchgeführt werden, ohne …

Investigating the dynamics of ion-surface interactions using electron-spin-polarized positively charged helium ions
… electrons from the surface. Energy conservation causes other electrons to be emitted, which are collected and their energy distributions analyzed. Because neutralization takes place outside the surface, this technique serves as a sensitive probe of that part of the material. The current studies …
