Threshold-Voltage Shifts in Organic Transistors Due to Self-Assembled Monolayers at the Dielectric: Evidence for Electronic Coupling and Dipolar Effects.
Mahdieh Aghamohammadi,Reinhold Rödel,Ute Zschieschang,Carmen Ocal,Hans Boschker,R. Thomas Weitz,Esther Barrena,Hagen Klauk +7 more
TL;DR: This work investigates transistors based on five oxide thicknesses and two SAMs with rather diverse chemical properties, using the benchmark organic semiconductor dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene, and finds that the dependence of the threshold voltage on the gate-dielectric capacitance is completely different for the twoSAMs.
Journal ArticleDOI
Interplay Between Fullerene Surface Coverage and Contact Selectivity of Cathode Interfaces in Organic Solar Cells
Antonio Guerrero,Bernhard Dörling,Teresa Ripolles-Sanchis,Mahdieh Aghamohammadi,Esther Barrena,Mariano Campoy-Quiles,Germà Garcia-Belmonte +6 more
TL;DR: It is demonstrated that a fullerene-rich interface at the cathode is a prerequisite to enhance contact selectivity and consequently power conversion efficiency.
Journal ArticleDOI
One‐Step Macroscopic Alignment of Conjugated Polymer Systems by Epitaxial Crystallization during Spin‐Coating
Christian Müller,Mahdieh Aghamohammadi,Scott Himmelberger,Prashant Sonar,Miquel Garriga,Alberto Salleo,Mariano Campoy-Quiles +6 more
TL;DR: In this paper, the conjugated polymer poly(3-hexylthiophene) (P3HT) as well as P3HT:fullerene bulk-heterojunction blends can be spin-coated from a mixture of the crystallizable solvent 1,3,5-trichlorobenzene (TCB) and a second carrier solvent such as chlorobenzenes.

Flexible low-voltage organic phototransistors based on air-stable dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT)
Johannes Milvich,Tarek Zaki,Mahdieh Aghamohammadi,Reinhold Rödel,Ulrike Kraft,Hagen Klauk,Joachim N. Burghartz +6 more
TL;DR: In this paper, high-performance, lowvoltage organic thin-film transistors based on dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) are thoroughly characterized with respect to their optical functionality.
