Current saturation and Coulomb interactions in organic single-crystal transistors
S. Fratini, H. Xie, I. N. Hulea +2
Electronic transport through rubrene single-crystal field effect transistors (FETs) is investigated experimentally in the high carrier density regime (n ~ 0.1 carrier/molecule). In…
Bias-dependent Contact Resistance in Rubrene Single-Crystal Field-Effect Transistors
A. Molinari, I. Gutierrez, I. N. Hulea +2
We report a systematic study of the bias-dependent contact resistance in rubrene single-crystal field-effect transistors with Ni, Co, Cu, Au, and Pt electrodes. We show that the re…
Reproducible Low Contact Resistance in Rubrene Single-Crystal Field-Effect Transistors with Nickel Source and Drain Electrodes
Iulian N. Hulea, Saverio Russo, Anna Molinari +1
We have investigated the contact resistance of rubrene single-crystal field-effect transistors (FETs) with Nickel electrodes by performing scaling experiments on devices with chann…
Doping, density of states and conductivity in polypyrrole and poly(p-phenylene vinylene)
I. N. Hulea, H. B. Brom, A. K. Mukherjee +1
The evolution of the density of states (DOS) and conductivity as function of well controlled doping levels in OC_1C_10-poly(p-phenylene vinylene) [OC_1C_10-PPV] doped by FeCl_3 and…
In situ determination of the energy dependence of the high-frequency mobility in polymers
I. N. Hulea, A. V. Pronin, H. B. Brom
The high-frequency mobility in disordered systems is governed by transport properties on mesoscopic length scales, which makes it a sensitive probe for the amount of local order. H…
Effect of dye doping on the charge carrier balance in PPV light emitting diodes as measured by admittance spectroscopy
I. N. Hulea, R. F. J. van der Scheer, H. B. Brom +3
Dye doping is a promising way to increase the spectral purity of polymer light-emitting diodes (LEDs). Here we analyze the frequency and field dependence of the complex admittance…
