Experimental Condensed Matter
Our research group is focused on understanding interconnecting atomic/morphological, electronic/magnetic and chemical/chemisorption properties of various surface/thin-film/nanophase systems using complementary experimental probes. This includes employing synchrotron-based-VUV photoemission (high-resolution and spin-resolved), -IR spectromicroscopy, -x-ray absorption, along with electron energy-loss spectroscopy, and variable-temperature scanning tunneling microscopy and atomic force microscopy. Systems that are currently being investigated include heteroepitaxially grown metal-on-metal (e.g. Ag/Cu, Co/Ag, Ag nanowires/Cu) and metal-on-semiconductor systems (e.g. Ag/GaAs, Be/Si), intermetallic alloy thin-film and surface systems (e.g. FeAl), simple and complex adsorbate and biological overlayers (amino acid/polymers/SiO2 and Au), polymer photo-induced degradation, and metal on metal-oxide nano-structures (e.g. Ag/Al2/O3/FeAl). Research emphasis is on correlating electronic/magnetic/photonic properties (hybridization, band-structure electron-phonon, electron-electron interactions) with atomic structure (STM, AFM, LEED, SEXAFS).
