Activities
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.
