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…
Tunable Frohlich Polarons in Organic Single-Crystal Transistors
I. N. Hulea, S. Fratini, H. Xie +5
In organic field effect transistors (FETs), charges move near the surface of an organic semiconductor, at the interface with a dielectric. In the past, the nature of the microscopi…
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…
