Ceramics on the basis of Yttrium-Aluminium-Garnets (YAG) are applied in the semiconductor industry, e.g. as support of Si wavers. During the etching process, physical and chemical interactions between the reactive plasma and the YAG surface appear, which determine the service life time of the components. A precise knowledge of the existing erosion mechanisms is the … Read more

Many perovskite (ABO3-structured) titanates are of great interest because of their exceptional electrical and dielectrical properties and, consequently, use or potential use in several electronic devices. Conventional solid state synthesis of these materials often requires high temperature in the range of 1000 – 1300 °C. As promising alternative, electric field assisted sintering, specifically flash sintering, … Read more

A conversion of the fossil fuels-based energy production to renewable resources is an ultimate goal to minimize emission of greenhouse gases. Since renewable energy sources such as wind and solar energy are usually not continuously available, to realize the energy transition, novel concepts for large-scale energy storage have to be developed. At IEK-14, we are … Read more

With an aim to address the climate crisis, the IEK-3 develops energy system models to analyze possible future energy systems with high shares of renewable energy in Germany and beyond. The main goal of the institute is to design cost-optimal and feasible energy systems which can aid decision-makers in politics and business. Rooftop photovoltaic (PV) … Read more
