Rogachev, Andrey | Admittance spectroscopy study of polymer diodes in small magnetic fields | We performed a systematic study of bipolar and unipolar organic diodes based on the p-conjugated polymer, 2-methoxy-5-(20-ethylhexyloxy) (MEH-PPV), using electronic and magneto-transport measurements with magnetic field in the range 0-180mT and admittance spectroscopy in the frequency range 1 Hz<f<1... | 2012-01-01 | |

Saam, Brian | Asymptotic and intermediate long-time behavior of nuclear free induction decays in polycrystalline solids and powders | Free induction decay (FID) measured by nuclear magnetic resonance (NMR) in a polycrystalline solid is the isotropic average of the FIDs for individual single crystallites. It has been recently proposed theoretically and verified experimentally that the long-time behavior of single-crystal FIDs has t... | 2012-01-01 | |

Rogachev, Andrey | Magnetic-field dependent differential capacitance of polymer diodes | Using admittance spectroscopy, we found that bipolar organic diodes based on pi-conjugated polymer, 2-methoxy-5-(20-ethylhexyloxy), MEH-PPV, have strong divergent contribution to the device differential capacitance. It is positive at low bias voltages, turns negative at intermediate biases, and beco... | 2012-01-01 |
