General Lab Information

X-Ray Scattering Group

The central objective of this group is to carry out basic studies of the structural, electronic and magnetic properties of condensed matter systems using synchrotron-based x-ray scattering techniques. Techniques include hard x-ray elastic scattering, pair distribution function (PDF), Bragg coherent diffraction imaging (BCDI) and resonant inelastic scattering, both with hard and soft X-rays. Structural investigations of polycrystalline and nano crystalline materials are aimed to understand crystal defects and disorder and how this changes in nanoscale materials.

Emphasis is also placed on electronic and magnetic structure and phase behavior, on electronic excitations in solids, on the investigation of surface and interfacial phenomena and nanoscale fluctuations in strongly correlated systems. New interest in the timescales of ordering and fluctuations has awoken with the introduction of X-ray Free-electron Lasers and X-ray time-correlation methods. The work is carried out in close collaboration with related efforts in CMPMSD and at BNL to address these questions.

In addition, the X-ray Scattering Group develops instrumentation. It has a strong partnership with beamlines at the National Synchrotron Light Source II, the Linac Coherent Light Source, and the Advanced Photon Source.
