Organic n-channel transistors based on core-cyanated perylene carboxylic diimide derivatives
Klaus Kern, Hagen Klauk, Marko Burghard, Ralf Thomas Weitz
Five core-cyanated perylene carboxylic diimides end-functionalized with fluorine-containing linear and cyclic substituents have been synthesized and employed in the fabrication of air-stable n-channel organic thin-film field-effect transistors with carrier ...
2008Quantum coherence and carriers mobility in organic semiconductors
Libero Zuppiroli, Marie-Noëlle Bussac, Jean-David Picon
We present a model of charge transport in organic molecular semiconductors based on the effects of lattice fluctuations on the quantum coherence of the electronic state of the charge carrier. Thermal intermolecular phonons and librations tend to localize p ...
2007Charge carriers photogeneration in pentacene field effect transistors
Mihai Adrian Ionescu, Costin Anghel
Organic FET transistors (OFETs) were fabricated on silicon substrates using pentacene as active organic layer and gold source and drain contacts. OFETs were used as test structures in order to study carriers photogeneration effect in organic layers. Photog ...
2007Thermopower measurements on pentacene transistors
Libero Zuppiroli, Marie-Noëlle Bussac, Adrian von Mühlenen
We present the first thermoelectric measurements on pentacene field effect transistors. We report high values of the Seebeck coefficient at room temperature between 240 and 500 micro V/K depending on the dielectric surface treatment. These values are indep ...
2007Trapping, self-trapping and the polaron family
The earliest ideas of the polaron recognized that the coupling of an electron to ionic vibrations would affect its apparent mass and could effectively immobilize the carrier (self-trapping). We discuss how these basic ideas have been generalized to recogni ...
IOP PUBLISHING LTD2007Interface issues in organic semiconductor based devices
The present doctoral thesis aims to contribute to the field of organic semiconductor physics and technology, both of which have become fast growing disciplines. Two technological applications are emerging from these research efforts: Organic light-emitting ...
EPFL2006De l'effet de la polarisation électronique sur le transport de charge dans les semi-conducteurs moléculaires
This work aims at a better understanding of transport mechanisms which take place in organic semiconductors such as pentacene. More accurately, we believe that the electronic polarization plays a leading part, which we try to identify in the particular cas ...
EPFL2006Polarization effects in the channel of an organic field-effect transistor
Libero Zuppiroli, Marie-Noëlle Bussac, Jean-David Picon, Hocine Houili
We present the results of our calculation of the effects of dynamical coupling of a charge carrier to the electronic polarization and the field-induced lattice displacements at the gate interface of an organic field-effect transistor (OFET). We find that t ...
