Our focus areas include correlated electron systems, topological matter, novel superconductors, and materials platforms for radiation detection.
Emerging Materials is a physics-based materials discovery program. Our objective is to develop a fundamental understanding of the electronic and/or magnetic behavior of complex materials including transition metal oxides, pnictides, chalcogenides, and main group halides.
Emerging Materials research emphasizes materials synthesis and growth of high quality single-crystal specimens as a means to reveal and understand new physics or new functionalities. Our strategy is to balance two modes of materials growth: discovery synthesis of new materials, and targeted growth of established systems that we modify and grow for specific test experiments.
Our group members have expertise in a wide range of growth techniques, with particular emphasis on:
- Floating zone growth, including growth at high oxygen pressures
- Flux growth of crystals both for targeted and discovery synthesis
- Bridgeman growth of pure, highly homogeneous crystals.
With an emphasis on developing structure-property relationships in complex materials, measurements in our group focus on structural determination using X-ray diffraction and detailed magnetic, transport, and thermodynamic characterization of samples.
We work closely on joint projects with other allied groups in the Materials Science Division, notably Neutron and X-ray Scattering, Superconductivity and Magnetism, Magnetic Thin Films, and Condensed Matter Theory, and through an international network of collaborators whose science complements our own capabilities. We are regular users of major DOE major facilities, primarily the Advanced Photon Source at Argonne and the Spallation Neutron Source at Oak Ridge National Laboratory.
