1Gondolo, PaoloDaily modulation due to channeling in direct dark matter crystalline detectorsThe channeling of the ion recoiling after a collision with a weakly interacting massive particle (WIMP) in direct dark matter crystalline detectors produces a larger scintillation or ionization signal than otherwise expected. Channeling is a directional effect, which depends on the velocity distrib...2011
2Vardeny, Zeev ValentineThe effects of charge injection in single-wall carbon nanotubes studied by charge-induced absorptionWe studied direct charge injection in a heterogeneous film of single-wall carbon nanotubes using the technique of charge-induced absorption. We found that the injected charges screen the excitons in the semiconducting tubes, reducing their binding energy and transferring oscillator strength from the...2011
3Vardeny, Zeev ValentineEvidence for excimer photoexcitations in an ordered ?-conjugated polymer filmWe report pressure-dependent transient picosecond and continuous-wave photomodulation studies of disordered and ordered films of 2-methoxy-5-(2-ethylhexyloxy) poly(para-phenylenevinylene). Photoinduced absorption (PA) bands in the disordered film exhibit very weak pressure dependence and are assign...2011
4Vardeny, Zeev ValentineStudy of magneto-electroluminescence and magneto-conductance in polymer light-emitting electrochemical cellsMagneto-electroluminescence (MEL) and magneto-conductance (MC) have been investigated in polymer light-emitting electrochemical cells based on ?super-yellow? poly-(phenylene vynilene) (SY-PPV). We measured positive MEL(B) and MC(B) responses that show a modified Lorentzian shape for B < 120 mT. At ...2011
5Gondolo, PaoloXENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: Examining the L eff dependenceWe consider the compatibility of DAMA/LIBRA, CoGeNT, XENON10 and XENON100 results for spin-independent (SI) dark matter weakly interacting massive particles, particularly at low masses (~10 GeV), assuming a standard dark matter halo. The XENON bounds depend on the scintillation efficiency factor Lef...2011
