Photonic Thin Film Systems

Scientific profile

The research group is engaged in the investigation of semiconductor thin films and nanostructures, in particular on the basis of silicon and transparent conductive materials for photonic components such as optical sensors on various carrier materials. The research of the group is based on a broad spectrum of physical and wet chemical coating and deposition processes (e.g. chemical vapor deposition (CVD), electron beam evaporation (EBE), atomic layer deposition (ALD), sputtering and inkjet printing). These approaches are combined with laser processes for the crystallization of semiconductors and the production of nanoparticles. This addresses applications in the field of smart textiles, environmental and medical technology. The research group investigates solutions for optical detection systems in biomedical imaging and analytical spectroscopy as well as concepts for the realization of energy-autonomous systems for individualized health monitoring.
