Be in the loop with antiferroelectrics
Prof. Dr. Brahim Dkhil University Paris-Saclay, CentraleSupélec Smart and Functional Materials Research Group Structures, Properties and Modeling of Solids Laboratory
Polarization-Electric field (P-E) loops can exhibit different shapes with some resembling to those of antiferroelectrics but without being antiferroelectric materials. I will discuss some of our recent works we did and are doing with antiferrroelectric and antiferroelectric-like materials and will highlight the role of defects or intermediate phases. Beyond energy storage applications, I will also show how these materials can be used for electrocaloric issues and how we can tune and play with these loops. I will also discuss some others potential applications we are interested in, such as memories and photo-based devices.
About the FLAME-inars
The FLAME-inars are organized by the collaborative project FLAME at TU Darmstadt, in which electronic-structure-property relationships are being developed and exploited to realize novel lead-free antiferroelectric compounds. The seminars will gather experts in processing, characterization and theory to discuss materials and applications, bulk and thin films, fundamental properties, electronic structure & defects, and related aspects.
