 | Vardeny, Zeev Valentine | Nonlinear optical spectroscopy of excited states in disubstituted polyacetylene | We used a variety of nonlinear optical (NLO) spectroscopies for studying the excited states order and primary photoexcitations in disubstituted polyacetylene (DPA). The NLO spectroscopies include ultrafast pump-probe photomodulation in a broad spectral range of 0.2-2.5 eV, two-photon absorption in... | 2010-05 | |

 | Miller, Joel Steven | Optical control of magnetization in a room-temperature magnet: V-Cr Prussian blue analog | We report reversible photoinduced magnetic phenomena for a V-Cr Prussian blue analog (Tc~350 K). This molecule-based magnet exhibits a decrease in magnetization upon illumination with UV light (λ~350 nm) and reaches a metastable state that has a long lifetime at low temperatures (>106 s at 10 K). ... | 2010-09 | |

 | Vardeny, Zeev Valentine | Optical studies of the charge transfer complex in polytiophene/fullerene blends for organic photovoltaic applications | We studied the photophysics of regioregular polythiophene/C61 (RR-P3HT/PCBM) blend films utilized for organic photovoltaic applications using the femtosecond transient and steady-state photomodulation techniques with above-gap and below-gap pump excitations and electroabsorption spectroscopy. We pro... | 2010-08 | |

 | Miller, Joel Steven | Pressure-induced phase transition in a molecule-based magnet with interpenetrating sublattices | The molecule-based magnet [Ru2(O2CMe)4]3[Cr(CN)6] contains two interpenetrating sublattices with sublattice moments confined to the cubic diagonals. At ambient pressure, a field of about 850 Oe rotates the antiferromagnetically coupled sublattice moments toward the field direction, producing a wasp... | 2010-05 | |

 | Scarpulla, Michael | Probing semiconductor band structures and heterojunction interface properties with ballistic carrier emission: GaAs/AlxGa1-xAs as a model system | Utilizing three-terminal tunnel emission of ballistic electrons and holes in a planar tunnel transistor with a Mott-barrier collector, we have developed a method to self-consistently determine the energy gap of a semiconductor and band discontinuities at a semiconductor heterojunction without using... | 2010-06 |
