Welcome !

This site gives you an overview of my research work which is devoted to bioelectronics and materials science. These disciplines are concerned with the preparation and adaption of functional materials to high-technology devices like biomolecular sensors, protective coatings, solar cells or numerous other applications.


The materials, from which microelectronic circuits and living cells are composed of, represent two highly complex material classes. Materials science has started to investigate how a convergence of both material worlds may be developed. The major application of such system lies currently in the area of biomolecular sensing and its usage in biotechnology and medicine. Also in this field thin films play an important role, since immuno-assays rely on thin anti-body layers in most cases. From the materials science point of view an understanding of the interface between biomolecules and semiconductor is the decisive question for the preparation and utilization of such hybrid devices.

Materials Research

An important role in materials sciences is played by thin films. These are both fascinating objects in modern science and essential ingredients to our technological way of life. By "thin" film a thickness between 0.000001 and 0.01 mm is meant (1 nm to 10 ┬Ám). What makes the field so exciting is that many future technology applications rely on new thin film systems that still have to be developed.

My research work has often been dealt with the structure and growth of thin films, the investigation of which was performed by x-ray diffraction and other structure sensitive techniques. More details can be found in the monograph
