High pressure synthesis & characterization of functional materials

The relation between electronic structure and the crystallographic atomic arrangement is one of the fundamental questions in condensed matter physics and inorganic chemistry. Since the discovery of the atomic nature of matter and its periodic structure, this has remained as one of the main questions regarding the very foundation of solid systems. Needless to say this has also bearings on physical and chemical properties of matter, where again the relation between structure and performance is of direct interest. Discoveries of novel properties and quantum states at high pressure may lead to new categories of material science frontiers.


High-pressure science is a fast developing new field in condensed matter physics and may even be regarded as the exploration of an entirely new dimension. This is to a large portion of course due to the development of the diamond anvil cell (DAC) technique with which one can easily control the pressure for systems of interest in the range of several mega bars and due to increasingly sophisticated synchrotron facilities to observe some of the drastic changes effected in the physical properties. With pressure, we can tune electronic, magnetic, structural and vibrational properties of condensed matter for a wide range of applications. Pressure has long been recognized as a fundamental thermodynamic variable, but whose use was previously limited by the available pressure vessels and probes. The development of megabar diamond-anvil cells (DACs) and associated in-laboratory and synchrotron techniques have opened a vast new window for exploiting the pressure variable in energy research. With the addition of the pressure dimension, can anticipate a marked increase in the number of materials and phenomena to be discovered than all that have been explored at ambient pressure.  Pressure drastically and categorically alters all phonon, electronic, magnetic, structural and chemical properties, and pushes materials across conventional barriers between insulators and superconductors, amorphous and crystalline solids, ionic and covalent compounds, and vigorously reactive and inert compounds. In the vast pressure dimension, the discovery of surprising high-pressure physical and chemical phenomena and the creation of novel materials become the rule rather than the exception. Exciting examples of pressure-induced phenomena include intermetallic compound-alloy transitions due to 4f electron delocalization, magnetic collapse in 3d transition elements, complication of “simple electron gas” metals, creation of record high-Tc superconductors, the fascinating polymorphism of simple molecular solids, and the discovery of compounds ultra-rich in hydrogen content. Many of these may have important energy implications limited only by imagination. The most promising is that an increasing number of novel materials with unique properties discovered at high pressures can be stabilized at low pressure; some of these can even be recreated through alternative chemical paths. Fundamental knowledge gained in high- pressure scientific exploration is also invaluable for energy considerations. This proposed symposium at EMRS 2016 Fall meeting would lead to an improved understanding and performance of materials at ambient and extreme conditions.
