Towards elastic ceramics and semiconductors — Yogendra Kumar Mishra, Thomas Preusse, Maria Claus, Charline Wolpert, Sebastian Wille, Sören Kaps, and •Rainer Adelung — Functional Nanomaterials, Institute of Materials Science, CAU Kiel, Germany

Designing a material that is elastic and can withstand high temperatures like 1000 °C or more is difficult to design, as polymers do decompose at lower temperatures and metals tend to melt. Especially under ambient conditions, often oxygen creates a problem for metals at these temperatures. Therefore, the design of a flexible ceramic material is desired. If it is at the same time a semiconductor, it has potential as a multifunctional material. In this presentation, we show how a ceramic material has to be organized to show bulk elasticity. In situ experiments show a semiconducting material bended with a manipulation needle in the scanning electron microscope. Furthermore, all details of the fabrication process and the microanalysis understood so far will be presented discussed.
