Electronic, Optoelectronic & Hybrid Devices

Mission & Goals

In the last few decades, the development in the field of electronic components has been primarily determined by the constant reduction in structure size. This is where new phenomena, caused for example by quantization effects, appear that need to be investigated, modeled and understood. In addition, the physical limits of scaling are now foreseeable. There is therefore a need for alternative solutions such as integrated optical and magnetic components that enable a further increase in the performance data of electronic systems in terms of speed, low power loss and cost reduction. The research area Electronic, Optoelectronic and Hybrid Components synoptically considers the entire chain of process, component, circuit and application in the system. To do this, we combine our expertise in technology, physical understanding and modeling based on this, technology-related circuit design and design methodology in order to develop improved or even completely new solutions. We help to improve the performance data of components from optoelectronics, bioelectronics, power electronics and microsystems technology. Another area that is becoming increasingly important is microstructured power electronic semiconductor components, for which we are developing powerful simulation platforms in order to simulate possible applications even under extreme conditions.
