Vardeny, Zeev Valentine | Absorption studies of charged excitations in α-sexithiophene | We present photoexcitation studies of vacuum deposited neutral films of α,ω-substituted sexithiophene (α-6T) using photoinduced absorption (PA) and PAdetected magnetic resonance spectroscopy (PADMR). We find evidence for photoinduced polarons having spin 1/2, with two absorption bands at 0.80... | alpha- sexithiophene; Charged excitations; Photoexcitation; Photoinduced absorption | 1996 |

Williams, Clayton C. | Evidence for internal electric fields in two variant ordered GaInP obtained by scanning capacitance microscopy | Single and two variant ordered GaInP samples are studied in cross section with the scanning capacitance microscope. Our study shows significant differences in the electronic properties of single and two variant GaInP. In unintentionally doped, ordered two variant samples, both n and p-type like do... | GaInP2; Atomic ordering; Internal electric fields; Scanning capacitance microscope | 1996 |

Williams, Clayton C. | Nanometer scale absorption spectroscopy by near-field photodetection optical microscopy | Near-field photodetection optical microscopy (NPOM) is a fundamentally new approach to near-field optical microscopy. This scanning probe technique uses a nanometer-scale photodiode detector which absorbs optical power directly as it is scanned in the near field of an illuminated sample surface. ... | Near-field photodetection optical microscopy; NPOM; Nanoscale; Photodiode | 1996 |

Mattis, Daniel C. | New mapping for particles on lattices with hard-core interactions | A novel mapping between Hilbert spaces of unequal dimensionalities yields many-body states which exactly satisfy the no-double-occupancy constraints for particles on lattices in arbitrary spatial dimensions. After proving the states are complete, we apply them to Nagaoka's theorem and the t-J model... | Ferromagnetism; Spin; Dimensions | 1996 |

Vardeny, Zeev Valentine | Optically detected magnetic resonance studies of undoped a-Si:H | Photogenerated carrier dynamics in undoped a-Si:H have been studied by photoinduced absorption (PA), photoluminescence (PL) and their respective optically detected magnetic resonances: PADMR and PLDMR. We have detected for the first time the "g = 4" resonance in PADMR in addition to the previously ... | Undoped a-Si:H; Amorphous silicon; Carrier dynamics | 1996 |

Vardeny, Zeev Valentine | Photoexcitation dynamics in C60-doped PPV under bias illumination | We have studied photoexcitation dynamics in pristine and C60-doped PPV films under bias Olumination by photoinduced absorption (PA), optically-detected magnetic resonance (ODMR), and electromodulated PA (EPA). Intrachain polaron pair species are the dominant excitations under these conditions. The p... | Photoexcitation dynamics; C60-doped PPV; Bias illumination; PPV films; Photoinduced absorption; ODMR; Electroabsorption | 1996 |
