Surface science and analytics
The main focal points of the Surface Science & Analytics group are (1) basic understanding
of self-assembly phenomena in ultrathin organic films on metal, semiconductor, and insulator substrates; (2)
modification of self-assembling monolayers (SAMs) by X-rays, electron irradiation, and plasma; (3) SAM-based lithography;
(4) design of monomolecular films for different applications, ranging from the fabrication of sensors and catalytically
active surfaces to molecular electronics; (5) X-ray and photoelectron microscopy characterization of ultrathin organic layers
and polymer films; (6) adsorption of organic molecules on organic surfaces; (7) adsorption of metals and fabrication of ultrathin
metallic films on monomolecular organic support; (8) spectroscopic characterization of liquids, and (9) spectroscopic characterization
of biologically-relevant objects and macromolecules in their natural environment.
The related activities take their course within several BMBF, DFG, and DAAD projects and include both experiments in the home laboratory
and XPS, NEXAFS, HRXPS, XES, PSD, XPM, and XAM studies performed at different synchrotron radiation facilities, including BESSY II in Berlin,
MAX-Lab in Lund (Sweden), ALS in Berkeley (USA), and NSRRC in Hsinchu (Taiwan). In the home laboratory, we have several specially designed,
multi-technique UHV installations on our disposal. These machines consist of several analysis, preparation, and load-lock chambers connected by
efficient sample transfer systems. They are equipped with a broad variety of complementary tools for surface analytics, such as, e.g., low-energy
electron diffraction, thermal programmed desorption, X-ray and ultraviolet photoelectron spectroscopy, ion scattering spectroscopy, work function measurements, and photoelectron emission microscopy.
In addition to the above scientific activities, the group conducts and participates in different industrial projects with national and
international partners. The group is involved in a broad world-wide scientific cooperation with partners from Germany, Italy, Sweden, Netherlands,
Switzerland, Poland, Russia, Israel, USA, Taiwan, and Japan. During last five years, we have published and submitted 67 manuscripts in reviewed,
high-rating journals and presented 88 contributions at different national and international conferences.
