Scattering Studies on Antiferroelectric Materials
Prof. Dr. Wolfgang Donner Institute of Materials Science Structure Research Division Technical University of Darmstadt
I will present a literature review of scattering experiments on antiferroelectric (AFE) materials; both the local and the global structure of AFE can be studied using electrons, photons and neutrons as a probe. Each method has its advantages and limitations, but their combination can provide valuable insight into the atomistic origin of the antiferrolectric instability as well as the ground state. Towards the end of the presentation I will also present some results on sodium niobate from my own group.
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.
