Kemerink, M. (author), Asadi, K. (author), Blom, P.W.M. (author), de Leeuw, D.M. (author)The availability of a reliable memory element is crucial for the fabrication of 'plastic' logic circuits. We use numerical simulations to show that the switching mechanism of ferroelectric-driven organic resistive switches is the stray field of the polarized ferroelectric phase. The stray field modulates the charge injection from a metallic...article 2012

(author)We investigate the modulation of the charge injection in organic field-effect transistors with self-assembled monolayers (SAMs) using both a bottom-gate and a top-gate geometry. The current modulation by using SAMs is more pronounced in the top-gate geometry due to the better defined upper surface of the bottom source and drain electrodes. By...article 2011

Asadi, K. (author), Wildeman, J. (author), Blom, P.W.M. (author), de Leeuw, D.M. (author), TNO Industrie en Techniek (author)Resistive switches have been fabricated using a phase-separated blend film of ferroelectric random copolymer poly(vinylidene fluoride-co-trifluoroethylene) with the organic semiconductor regio-irregular poly(3-hexylthiophene) (rir-P3HT). Spin-coated blend films have been contacted with symmetrical Ag top and Ag bottom electrodes, yielding...article 2010

Zhang, Y. (author), Blom, P.W.M. (author), TNO Industrie en Techniek (author)The hole injection in Schottky barriers formed between p -type doped regioregular poly(3-hexylthiophene-2,5-diyl) (rr-P3HT) and silver (Ag) is investigated. The rr-P3HT is controllably doped using the acceptor 2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4-TCNQ). We demonstrate that only one order of magnitude increase in the...article 2010

Asadi, K. (author), de Boer, T.G. (author), Blom, P.W.M. (author), de Leeuw, D.M. (author), TNO Industrie en Techniek (author)Organic non-volatile resistive bistable diodes based on phase-separated blends of ferroelectric and semiconducting polymers are fabricated. The polarization field of the ferroelectric modulates the injection barrier at the semiconductor-electrode contact and, hence, the resistance of the comprising diodes. Comparison between the on- and off...article 2009
