From Pnictides to Perovskites: Impact of Local Structure in Solid State Chemistry (#62)

Inorganic crystalline solids (such as oxides, chalcogenides, intermetallics etc) exhibit a number of unique electronic, optical, magnetic, dielectric, catalytic properties that can, in general, be well described by models based on a simple structure with a periodic arrangement of atoms. However, there is a growing awareness of the importance of local structural features in controlling the properties of condensed phases. This includes phenomena such as short-range ordering, local distortions, including unusual coordination environments and mixed valency. A significant challenge in contemporary solid state and materials chemistry is to develop synthetic methods, including those based on high temperature reactions, solvothermal reactions, chimie douce, and high-pressure synthesis, to control local structures. Of equal importance is the development of precise and in-depth structural characterization tools including X-ray and neutron total scattering, X-ray Absorption Spectroscopy and computational methods that allow for a deeper understanding and prediction of the nature of chemical bonds, electron-electron interaction, and functionalities. This symposium aims to bring experimental and theoretical solid state chemists, physicists and materials scientists together to discuss latest advances and challenges related to the local structure in solid state chemistry across a range of current materials including ferroelectric and magnetic perovskites and superconducting pnictides.
