Motivation and Research Strategy

The work of the Institute of Electronic and Sensor Materials focuses on interface and surface chemistry of materials. A wide range of surfaces of different materials is researched. The university's own clean room is available for special work. It is operated jointly with the institutes of applied and experimental physics. The "Reiche Zeche" research and teaching mine is also used for experiments.

The core fields of application of functional materials determined by interfaces are information and communication technologies as well as energy, environmental and health-related applications. In particular, heterogeneous catalysis, chemical sensors, actuators, gas storage and separation, molecular electronics and functional surface coatings are of interest. The determination of structure-function relationships is fundamental for the development of such functional materials. To achieve this, the combination of intelligent chemical material synthesis, extensive material characterization and subsequent functional testing is necessary.

The correlation of all results gives us insight in the structure-function-relationships of the material and therefore strategies to develop materials with better performances.
