    • Electrical characterization of conducting polypyrrole by THz time-domain spectroscopy 

      Jeon, Tae-In; Grischkowsky, D.; Mukherjee, A. K.; Menon, Reghu (AIP Publishing, 2000-10-16)
      Using an optoelectronic THz beam system for THz time-domain spectroscopy (THz TDS), we have measured the absorption and index of refraction of a conducting polypyrrole film from low frequencies to 2.5 THz. From these ...
    • Synthesis of ZnO nanocrystals by subsequent implantation of Zn and O species 

      Lee, J. K.; Tewell, C. R.; Schulze, R. K.; Nastasi, M.; Hamby, D. W.; Lucca, D. A.; Jung, H. S.; Hong, K. S. (AIP Publishing, 2005-04-29)
      We report the preparation of ZnO nanocrystals embedded in a SiO2 matrix formed using sequential zinc and oxygen ion implantations. The optical absorption spectra and photoemission spectra of zinc implanted and zinc/oxygen ...
