Electronic Materials and Applications 2021 (EMA 2021) is an international conference focused on electroceramic materials and their applications in electronic, electrochemical, electromechanical, magnetic, dielectric, biological and optical components, devices, and systems. Jointly programmed by the Electronics Division and Basic Science Division of The American Ceramic Society, EMA 2021 will be a virtual event on the same planned dates, January 19–22, 2021.
The conference program features 15 symposia covering a range of focused topics.
We participate in symposium S11 – Dislocations in Ceramics: Processing, Structure, Plasticity, and Functionality
In the field of functional ceramics, the importance of dislocations for materials processing and properties recently gained attention. For example, some oxides were discovered to allow considerable plastic deformation, even at room temperature as, for example, in single-crystalline strontium titanate.
Beyond purely mechanical considerations of plasticity in oxides, particular interest lies in the impact of dislocations on functional properties as, for example, thermal, electronic and ionic conductivity, and ferroelectricity. The foundation of this impact is related to the atomic structure, chemistry, and charge of dislocations in oxides, their percolation, and their response to mechanical, electrical, thermal, and chemical parameters.
Beyond properties, dislocations are considered to be of central importance for processing, for example, in the field of sintering and flash sintering, high-pressure powder processing, and aerosol deposition. These methods offer the potential to engineer materials, phases, and structures with new functionality while overcoming limitations of conventional processing.
This symposium brings together experimentalists and modelers in the field of dislocations in functional materials. While the focus is on functional oxides, many concepts in this field are well established for metals. Accordingly, related contributions from other materials including metals are welcome as well.
