Prof. Dr. Helmut Zacharias
The research group "Generation of ultrashort laser pulses and its application" of Prof. H. Zacharias focuses on physical and chemical processes upon, within and underneath surfaces and interfaces. A goal is to contribute in understanding catalytic surface reactions. For this approach the group designs and develops compact femtosecond laser systems at high repetition rates, short pulse duration and high pulse energy. These ultrashort laser pulses can be used to generate soft and hard x-ray pulses which on the other hand enable time-resolved experiments with a comparable high time resolution.

Dr. Harry Mönig
The research group "Nanoscale Interface Analytics" focuses on investigations of the structural, chemical, and electronic properties of organic, inorganic and hybrid interfaces on the nanometer scale. We perform complementary scanning probe microscopy- and photoelectron spectroscopy experiments under ultrahigh vacuum conditions to study interfaces with high technological relevance (e.g. for solar cells or light emitting diodes) under defined conditions. Our approach with locally resolved and integral measurement techniques is a powerful combination, which satisfies the high demand for a controlled material and interface engineering on a nanometer scale.

PD Dr. André Schirmeisen
The work in the nano-mechanics group of PD Dr. A. Schirmeisen is characterized by the application of scanning probe microscopy (SPM) methods to modern issues of surface science and nanostructured materials. The research is focused towards the analysis of surface properties with atomic force microscope (AFM). From the different types of interaction forces (electrostatic, magnetic, chemical, ...) a lot can be learnt about the physical mechanisms governing nanoscale contacts.

Dr. Daniel Wegner (PI)
The goal of the research group of Dr. D. Wegner is the bottom-up fabrication of nanoscopic magnets from single atoms and molecules and their analysis by scanning probe techniques. Therefor they use a commercially available low-temperature Scanning Tunneling Microscope (LT-STM) system, the Createc LT-STM. The STM is not only a microscope but also a versatile tool so that many additional experiments can be realized with the STM. The new invented nanomagnetic material has great potential for future applications in data storage and processing (spintronics) as well as quantum computing.
