1 Lupton, John MarkEfficient dipole-dipole coupling of Mott-Wannier and Frenkel excitons in (Ga,In)N quantum well/polyfluorene semiconductor heterostructuresWe investigate interactions between Mott-Wannier (MW) and Frenkel excitons in a family of hybrid structures consisting of thin organic (polyfluorene) films placed in close proximity (systematically adjusted by GaN cap layer thickness) to single inorganic [(Ga, In)N/GaN] quantum wells (QWs). Charac...Mott-Wannier; Frenkel; Excitons; Dipole-dipole coupling; Semiconductor heterostructures2007-07
2 Vardeny, Zeev Valentine; Ehrenfreund, Eitan A.Illumination-induced metastable polaron-supporting state in poly(p-phenylene vinylene) filmsWe found an illumination-induced metastable polaron-supporting state in films of a soluble derivative of poly-p-phenylene vinylene (MEH-PPV). Pristine, nonilluminated MEH-PPV polymer films do not show longlived photogenerated polarons. Prolonged UV illumination, however, is found to induce a revers...Metastable polaron-supporting state; Poly(p-phenylene vinylene); PPV; MEH-PPV; Excitons2007-07
3 Mishchenko, Eugene; Raikh, Mikhail E.Smearing of the two-dimensional Kohn anomaly in a nonquantizing magnetic field: implications for interaction effectsThermodynamic and transport characteristics of a clean two-dimensional interacting electron gas are shown to be sensitive to the weak perpendicular magnetic field even at temperatures much higher than the cyclotron energy, when the quantum oscillations are completely washed out. We demonstrate this ...Kohn anomaly; Tunnel density of states2007-07
4 Caserta, Michael; Lund, Dale A.Toward the development of an inventory of daily widowed life (IDWL): guided by the duel process model of coping with bereavementThe Dual Process Model of Coping with Bereavement (Stroebe & Schut, 1999) suggests that the most effective adaptation involves oscillaton between two coping processes: loss-orientation (LO) and restoration-orientation (RO). A 22-item Inventory of Daily Widowed Life (IDWL) was developed to measure t...Bereavement; Grief reaction; Widowhood; Psychological orientation; Adaptation, Psychological2007-07
5 Millgram, ElijahWho was Nietzsche's genealogist?Nietzsche's Genealogy of Morals is deservedly part of the ethical canon, but it is also enormously and insistently absent-minded. I'm going to first present, as a textual puzzle, a handful of forgetful moments in the first two essays of the Genealogy. To address the puzzle, I will take up a familiar...2007-07
