Inorganic Chemistry

New and higher-performing materials play a key role in enabling new technology. Central to achieving this goal is a detailed understanding of the impact that structure and composition have on physical properties. To that end, the research conducted in our group broadly focuses on understanding the interplay between spin, charge, and lattice degrees of freedom in the solid state so as to better design new and improve existing functional materials. A few examples of which are outlined below. We use a large variety of synthetic methods to prepare new materials; including high-temperature ceramic as well as hydrothermal routes. We place equal emphasis on the preparation of materials and their complete physical characterization which includes an accurate determination of: the underlying crystal structure, magnetism, electrical transport, dielectric properties, and electrochemical performance. We also make extensive use of a variety of density functional theory (DFT) computational tools in order to understand the nature of chemical bonding in these materials.
