 | Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Photomodulation spectroscopy of iodine-doped polyacetylene; phase transition from soliton lattice to metal | Using the photomodulation technique for iodine I3-)-doped polyacetylene, we have found spectroscopic evidence for an abrupt phase transition at 5% I3-. The transition is from the lightly doped phase best described as soliton lattice to the heavily doped metallic phase. The phase transition is chara... | Photomodulation spectroscopy; Iodine-doped polyacetylene | 1986-10 |

 | Vardeny, Zeev Valentine | States in the gap of doped and undoped a-Si:H studied by the photomodulation spectroscopy | The steady state photomodulation spectrum, its temperature and excitation intensity dependences have been studied in phosphorous doped and undoped a-Si:H. The spectra are analyzed in terms of photocarriers trapped in band-tail states and dangling bonds (DB) defects in undoped samples and impurities ... | Doped a-Si:H; Undoped a-Si:H; Amorphous silicon; Photomodulation spectroscopy; Mobility gap; Steady state photomodulation spectrum | 1987 |

 | Scarpulla, Michael | Synthesis and optical properties of II-O-VI highly mismatched alloys | We have synthesized ternary and quaternary diluted II-VI oxides using the combination of O ion implantation and pulsed laser melting. CdOxTe12x thin films with x up to 0.015, and the energy gap reduced by 150 meV were formed by O1-implantation in CdTe followed by pulsed laser melting.
