My research is focused on using polyoxometalates and other solution precursors for the deposition of thin films for advanced electronic and energy applications. I am particularly interested in materials that show memristive behavior, such as TiO2 and Ta2O5. I am also interested in materials that exhibit electrochromism or thermochromism, for potential use in energy-saving smart windows. The main solution deposition techniques I use include spin coating for smaller substrates, and aerosol or mist coating for larger substrates. Much of my thin-film characterization work involves X-ray diffraction, X-ray reflectivity, and spectroscopic ellipsometry. I also frequently use AFM, SEM, and TEM for sample imaging.
