X-ray diffraction and crystal chemistry studies of the atomic arrangements in various intermetallic compounds containing aluminum, rare earths, or other metals are being carried out. Each material presents some interesting challenges. Some materials exhibit twinning, some are high temperature phases, and some have large unit cells. Of interest are the quasicrystalline phases which exhibit symmetries forbidden in crystalline structures. Methods for the study of the structures of these strange materials are being studied. In addition to X-ray diffraction techniques, synchrotron radiation measurements are frequently employed to characterize them.
Learn the basics of crystallography and X-ray diffraction by working on specific problems in crystal structure determination and crystal chemical studies through reading, studying, and regular discussions with the mentor. Develop creative views of the relationships between the structures of a host of intermetallic compounds.
