Research Interests

Studies of high temperature superconductors, magnets, ferroelectrics in transition metal oxide compounds where strong electron correlations dominate the physics. We apply a wide range of experimental probes to materials made in our laboratory. Materials capabilities include the control of oxygen stoichiometry using electrochemistry and ozone treatments and the growth of high quality oxide films. Film studies include how the strain, low-dimensionality, and constraint of epitaxy control material properties and phase transitions.

Research highlights: early studies of the symmetry of the superconducting gap in copper oxide superconductors with Angular-Resolved Photoemission, the study of the dispersion of a single hole in an insulating copper-oxide Рparent material to high temperature superconductors, studies of oxygen staging and large-scale electronic phase separation in oxygen doped La2-xSrxCuO4+y high temperature superconductor, control of structural phase transitions via strain and epitaxy in ferroelectric and related films, separation of finite-size and strain effects on the magnetism of ferromagnetic oxide films.
