Session Overview |
Session | ||
MS-14: Perovskites
Invited: James Rondinelli (USA), Joke Hadermann (Belgium) | ||
Session Abstract | ||
A fundamental understanding of the relationship between the crystal structure, and the electronic and magnetic structures, electronic processes, phase boundaries and phase transformations, is at the heart of the developments to design perovskite systems with enhanced or novel functions able to lead to application breakthroughs. This symposium will explore the structure property relationships in perovskites, including in halide systems. For all abstracts of the session as prepared for Acta Crystallographica see PDF in Introduction, or individual abstracts below. | ||
